Bonne nuit is the classic way to say good night in French. Easy, useful, and slightly more specific than many learners expect.
Here’s the important bit: French speakers do not use bonne nuit the same way English speakers use “good night” in every evening situation. If people are still hanging out, chatting, eating dessert, or pretending they are definitely not about to watch one more episode, bonne soirée is often the better choice.
So yes, one tiny phrase can cause surprisingly large amounts of awkwardness. Very French of it.
In this guide, you’ll learn when to use bonne nuit, what to say before bed, how to sound natural, and which bedtime phrases are sweet, polite, casual, or just plain useful. If you want more French basics after this, you can also explore the main Learn French hub.
What Does Bonne Nuit Mean?
Bonne nuit means good night.
Pronunciation: bun nwee
It is used when someone is going to bed, heading home to sleep, or ending the day for real. Think of it as “sleep well, night is here, we are done being awake humans.”
| French | Pronunciation | Meaning | Example Sentence | Translation | Learner Note |
|---|---|---|---|---|---|
| Bonne nuit | bun nwee | Good night | Bonne nuit, à demain matin. | Good night, see you tomorrow morning. | Use it when parting for the night or going to bed. |
Bonne Nuit Vs Bonne Soirée
This is the mistake English speakers make all the time.
Bonne soirée means something like have a good evening. You say it when the evening is still going on. Bonne nuit comes later, when it is actually bedtime or close to it.
| Phrase | Pronunciation | Meaning | When To Use It | Example | Learner Note |
|---|---|---|---|---|---|
| Bonne soirée | bun swah-ray | Have a good evening | When leaving someone in the evening but not at bedtime | Bonne soirée, amuse-toi bien. | Very common in shops, restaurants, and social situations. |
| Bonne nuit | bun nwee | Good night | When someone is going to sleep or ending the night | Bonne nuit, dors bien. | More final than bonne soirée. |
For example, if you leave a restaurant at 8:30 p.m., the server will probably say bonne soirée, not bonne nuit. If you say goodnight to your partner before turning off the light, bonne nuit is perfect.
Quick Rule: If the evening is still alive, use bonne soirée. If everyone is clearly done and heading to sleep, use bonne nuit.

How To Pronounce Bonne Nuit
Bonne sounds roughly like bun.
Nuit sounds roughly like nwee.
Together: bun nwee.
The final t in nuit is usually silent. French loves silent letters almost as much as it loves making learners suspicious of spelling.
Also notice there is no article here. You do not say something like “the good night.” Just bonne nuit.
