The direct way to say good night in French is bonne nuit. Say it when someone is going to sleep, when you leave them for the night, or when you are ending a late message with a bedtime wish. Do not use it as your standard evening hello. For that, French uses bonsoir.
The difference is small on paper and very visible in real life. Bonsoir starts an evening interaction. Bonne nuit closes the day and points toward sleep. Learn that contrast and you avoid one of the most common greeting mix-ups for English speakers.
Quick answer: is it bonne nuit or bonsoir?
Use bonsoir /bɔ̃.swaʁ/ to greet someone in the evening. Use bonne nuit /bɔn.nɥi/ when they are going to bed or when you are wishing them a good night's sleep. If you are leaving a restaurant at 22:00 but the other person is still working, say bonsoir or au revoir, not automatically bonne nuit.
| Situation | Natural French | Why |
|---|---|---|
| You arrive at a dinner at 20:00 | Bonsoir! | You are beginning an evening interaction |
| You leave your host after dinner | Bonne soirée, au revoir! | You wish them a good rest of the evening |
| Your child goes to bed | Bonne nuit! | Sleep is next |
| You end a late text to a friend | Bonne nuit, dors bien. | You are wishing sleep |
| You leave a hotel reception at 23:00 | Bonsoir / bonne soirée | The receptionist is not necessarily going to bed |
The Académie française describes bonsoir as the politeness formula used to greet someone at the end of the day. Its entry for nuit gives bonne nuit as a wish for the time devoted to sleep or rest. The two phrases are close cousins, but they do different social jobs.
When should you say good night in French?
Use bonne nuit only when sleep or the end of the day is the point. If you are greeting someone after dark, choose bonsoir. If you are leaving them to continue their plans, choose bonne soirée. This quick choice makes good night in French sound natural instead of translated.
Bonsoir: your evening hello
Think of bonsoir as “good evening” first. You use it on arrival, when you open a call, when you start a service interaction, and when you meet someone after daytime has shifted into evening.
You, entering a restaurant: Bonsoir, nous avons une réservation.
Host: Bonsoir. À quel nom?
You can also say it to a neighbor in the hallway, a colleague arriving for an evening event, or a friend meeting you outside a cinema. It is neutral and polite. Add madame or monsieur when you need to address a stranger respectfully.
CNRTL notes that bonsoir is a salutation at the end of the day, and it can be a simple formula of politeness rather than a literal wish (CNRTL, bonsoir). That is why it works so well as an opening.
Can bonsoir also be a goodbye?
Sometimes. You may hear it at the end of an interaction, especially in a brief exchange. But do not rely on it as your main farewell formula. Au revoir is the dependable neutral goodbye. Bonne soirée is the warmer choice when you are leaving someone to continue their evening.
Bonsoir, madame., Bonsoir.
Merci, bonne soirée., Merci, à vous aussi.
This pair gives you a simple pattern: bonsoir when contact begins; bonne soirée when you wish the person a pleasant evening after you part.
Bonne nuit: save it for sleep
Bonne nuit is a wish for the night ahead. The key idea is not darkness. It is rest, sleep, or the end of the day for that person.
Say it to a partner before lights out, to children at bedtime, to a friend leaving your apartment very late, or in a text when you know the conversation is ending for the night.
Bonne nuit, à demain.
Bonne nuit, dors bien.
Bonne nuit tout le monde!
The Académie's current entry explicitly gives Je vous souhaite une bonne nuit and the shorter Bonne nuit! among expressions around sleep and nighttime rest. That is useful reassurance: your instinct to use it at bedtime is exactly right.
Why bonne nuit can sound odd at a restaurant
At 23:30 you may be tired and ready for bed. The person serving you may still have a shift, a commute, and a very different night ahead. Saying bonne nuit to them can feel like you are assigning them bedtime.
Use bonne soirée instead. It is warm and correct even when the evening is nearly over:
Merci beaucoup. Bonne soirée!
If it is well after midnight, bonne nuit can be more plausible, but context still wins. Follow the room. If the server says bonne soirée, mirror it.
The third phrase learners need: bonne soirée
Many English speakers try to make bonne nuit cover “have a good evening.” French already has a precise phrase: bonne soirée.
| Phrase | Literal idea | Use it when |
|---|---|---|
| Bonsoir | good evening | Greeting someone in the evening |
| Bonne soirée | have a good evening | Leaving someone before their evening is over |
| Bonne nuit | have a good night | They are going to sleep or ending their day |
This one table solves most of the confusion. You do not need to turn it into a grammar rule. Just ask one question: am I arriving, leaving them to their evening, or wishing them sleep?
Examples that sound natural
At an evening class:
Bonsoir tout le monde!
Leaving friends at 21:30:
Merci pour ce soir. Bonne soirée!
Leaving a friend's home at 00:30:
Bonne nuit, rentre bien!
A late text:
Je vais dormir. Bonne nuit, à demain.
A host welcoming you at 19:30:
Bonsoir, entrez!
The phrase changes because the action changes, not because a clock dictates it.
Formal, informal, and affectionate night wishes
The basic words work across many relationships. Add a little only when it matches the connection you already have.
Neutral and polite
- Bonne nuit.
- Je vous souhaite une bonne nuit.
- Bonne soirée, au revoir.
- À demain. Bonne nuit.
Je vous souhaite une bonne nuit is courteous but more formal than most family conversations. It could fit a host, an older relative, or a written note. In speech, the shorter version usually feels more natural.
Informal and friendly
- Bonne nuit, dors bien.
- Bonne nuit, fais de beaux rêves.
- Bonne nuit, à demain!
- Passe une bonne nuit.
Fais de beaux rêves means “have sweet dreams.” Use it with friends, a partner, or children. It can feel too intimate for a new acquaintance or a coworker, so keep it in the friendly lane.
To a group
- Bonne nuit tout le monde!
- Bonne soirée à tous!
- Rentrez bien, bonne soirée!
The simple plural gesture matters more than complicated vocabulary. If you are leaving a small dinner, add merci pour ce soir and you have a complete, gracious exit.
Pronunciation: three phrases, three mouth patterns
Bonsoir /bɔ̃.swaʁ/
The opening bon uses a nasal vowel. Do not pronounce a clear final n. The second syllable has the glide /w/ found in “wa” but with a French r at the end. Say it in two connected beats: bon | soir.
Bonne nuit /bɔn.nɥi/
Here the n is pronounced. That is a useful contrast with bonsoir. In bonne, the double n does not make two consonants, but it keeps the vowel oral: /bɔn/. Then nuit begins with /n/ and includes the French /ɥ/ glide, close to saying “wee” with rounded lips.
Take it slowly:
bonne | nuit
Round your lips for the start of nuit. If /ɥ/ feels difficult, aim for a light “nwee” rather than freezing. Clear rhythm is more valuable than a tense mouth.
Bonne soirée /bɔn swa.ʁe/
The final ée is /e/, a clean closed vowel. Do not turn it into the English diphthong in “day.” Let the phrase flow in three small groups: bonne | soi | rée.
For more sound work, French pronunciation for English speakers gives you a practical way to train nasal vowels, the French r, and connected rhythm without trying to fix everything at once. A short French rhythm and intonation drill will help the three farewells land with a natural closing tone.
Choose the scene first
Before you practice the words, picture the scene: arriving, leaving, or going to sleep. The right image will cue the right phrase faster than a translation list.
A five-minute good-night-in-French drill
Minute 1: sort the situations
Read the situation, pause, then answer aloud:
- You enter a cinema at 20:15: Bonsoir!
- You leave a friend's dinner at 22:00: Bonne soirée!
- Your roommate goes to bed: Bonne nuit!
- You end a video call at 00:15: Bonne nuit, à demain.
- You meet a hotel receptionist at 19:00: Bonsoir.
Do the set twice with the text covered. The goal is quick selection, not a fast voice.
Minutes 2 and 3: shadow the rhythm
Say each line five times. First slow, then natural, then with a small pause before the second clause.
Bonsoir, nous avons une réservation.
Merci pour ce soir. Bonne soirée!
Bonne nuit, dors bien.
À demain. Bonne nuit!
Notice that French does not need dramatic stress on bon. Keep the line even, then let the final word carry a small closing fall.
Minute 4: repair the common mix-up
Say the wrong phrase first, then fix it immediately:
- Arriving at dinner: bonne nuit → bonsoir.
- Leaving a bar at 21:00: bonne nuit → bonne soirée.
- Tucking in a child: bonsoir → bonne nuit.
Training the correction is useful. In real conversation, you can recover gracefully if you choose the wrong one.
Minute 5: make a closing message
Record a 15-second message to a friend. Thank them for the evening, say what happens next, and choose the right close. For example: Merci pour ce soir, c'était super. Je rentre. Bonne soirée, à bientôt! Then make a second version for bedtime: Je vais dormir. Bonne nuit, à demain.

Common mistakes with bonne nuit and bonsoir
Using bonne nuit as an evening hello
It is understandable, but it creates a strange image: you are wishing sleep at the beginning of the evening. Use bonsoir on arrival.
Saying bonsoir at bedtime
Bonsoir can be a polite greeting, but it does not specifically wish rest. When the person is climbing into bed, bonne nuit is warmer and more exact.
Forgetting bonne soirée
This is the missing middle phrase. It lets you leave politely before bedtime. Put it into your active vocabulary now and you will use it often. For more useful departure language, add a few scene-based phrases from French for travel.
Trying to sound intimate too soon
Fais de beaux rêves is lovely, but it has a personal tone. With a hotel host, teacher, or new colleague, bonne soirée or bonne nuit is plenty.
The takeaway
Good night in French is bonne nuit. Save it for sleep and the end of the day. Use bonsoir to say good evening when you meet someone, and bonne soirée when you are leaving them to enjoy the rest of their evening.
Practice the three phrases as a set, attached to scenes you know. Then use the French speaking practice guide to add a few daily recall repetitions. A short, well-timed farewell does more for your French than a complicated sentence said at the wrong moment.
A helpful late-evening fallback
If you are unsure at the moment of leaving, say merci, bonne soirée. It is safe when the other person is still out, working, hosting, or simply continuing their plans. Save bonne nuit for the point where sleep is clear. This is not about finding a perfect clock time. It is about matching your wish to the person's next moment.
