Imagine you leave your French friends after sharing a drink with them, youβve already said goodbye in French, and now want to add βhave a good nightβ in French.
This article features audio recordings. Click the blue text next to the headphone to hear me say that word or sentence in French.
Note that when applicable, I used a modern spoken French pronunciation.
Youβve learned in your French studies that βnightβ was βla nuitβ in French. So you prepare your sentence, place the irregular adjective before the noun, do the agreement (kiddos!!), and wish them a confident βbonne nuitββ¦ and they all start laughing.
What went wrong?
How to Say Good night in French?
To answer this, we need to compare the intent behind βgood nightβ in French and in English.
Good night in English
In English, it is quite common to say βgood nightβ as in βenjoy the rest of the nightβ, the night here referring mostly to the social evening.
Good night in French
Well, the good news is that itβs common to do this in French as well.
The bad news is that you canβt translate literally.
In French, thereβs a different expression used for hoping that someone will enjoy the rest of their social night, and it doesnβt involve the word βnightβ.
If you translated βgood nightβ literally in French youβd get βbonne nuitβ. Pronounce it like [bun nwee].
Unfortunately, βbonne nuitβ means βsleep wellβ. Itβs what you say to someone before they go to bedβ¦. π€
Before leaving someone who is going to bed, the French usually say : βbonne nuitβ: have a good nightβs sleep.
We may add βfais/faites de beaux rΓͺvesβ: sweet dreams!
You imagine that if you were to say βbonne nuitβ to someone who is going out for the night; it may come as a surpriseβ¦ And surprise is often met with laughter.
Theyβre not laughing at you. Theyβre laughing because you said something unexpected, something that got lost in translation.
Please donβt take it personally, laughter is only a human response to surprise. It may not be a pleasant experience to feel laughed at but itβs likely there will be many occasions in your French journey that youβll make a fool of yourself. Trust me, Iβve been there many times in English! So better grow a thicker skin right now and learn to laugh with everybody.
So if βhave a good nightβ is not βbonne nuitβ, then what should you say?

Have a Good Night in French = Bonne SoirΓ©e
When wishing someone a good night as a pleasant evening, you should say βBonne soirΓ©eβ.
βUne soirΓ©eβ is an evening span. You could say:
- Bonne soirΓ©e
Have a good evening - Passe/ passez une bonne soirΓ©e
Have a good evening - Je te/vous souhaite une bonne soirΓ©e
Literally, I wish you to have a good evening
If you are relating your evening, you could say:
- Jβai passΓ© une (trΓ¨s) bonne soirΓ©e avec Pierre
I had/enjoyed a (very) good evening with Pierre.
or on the contrary
- Quelle mauvaise soirΓ©e ! Jβai vraiment passΓ© une soirΓ©e nulle avec Pierreβ¦
What an unpleasant evening! I really had a bad time with Pierre.
Note that in French, βune soirΓ©eβ is also a party. Of course the French would associate evening time with partying, right?
When To Use βBonsoirβ in French?
Wait! What about βbonsoirβ? Can you use βbonsoirβ to say βgood nightβ in French?
Yes you can. But βbonsoirβ is more of a greeting, or way to say hello in French when you arrive somewhere in the evening, or sometimes βgoodbyeβ when you leave in the evening.
Originally, of course βbonsoirβ does mean βbon soirβ = βgood eveningβ. But now, itβs rather βflatβ: you are not really expressing the notion of βI wish you a pleasant eveningβ β youβre just saying βhiβ or βbyeβ using an appropriate expression for the time of the day.
In Short
Here is what you should memorize to avoid faux pas.
- Bonsoir = hi or bye in the evening π
- Bonne soirΓ©e = have a pleasant evening π»πΊπ
- Bonne nuit = enjoy a good night sleep / sleep well π΄
