Imagine you leave your French friends after sharing a drink with them, youโve already said goodbye in French, and now want to add โhave a good nightโ 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.
Youโve learned in your French studies that โnightโ was โla nuitโ in French. So you prepare your sentence, place the irregular adjective before the noun, do the agreement (kiddos!!), and wish them a confident โbonne nuitโโฆ 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 โgood nightโ in French and in English.
Good night in English
In English, it is quite common to say โgood nightโ as in โenjoy the rest of the nightโ, the night here referring mostly to the social evening.
Good night in French
Well, the good news is that itโs common to do this in French as well.
The bad news is that you canโt translate literally.
In French, thereโs a different expression used for hoping that someone will enjoy the rest of their social night, and it doesnโt involve the word โnightโ.
If you translated โgood nightโ literally in French youโd get โbonne nuitโ. Pronounce it like [bun nwee].
Unfortunately, โbonne nuitโ means โsleep wellโ. Itโs what you say to someone before they go to bedโฆ. ๐ค
Before leaving someone who is going to bed, the French usually say : โbonne nuitโ: have a good nightโs sleep.
We may add โfais/faites de beaux rรชvesโ: sweet dreams!
You imagine that if you were to say โbonne nuitโ to someone who is going out for the night; it may come as a surpriseโฆ And surprise is often met with laughter.
Theyโre not laughing at you. Theyโre laughing because you said something unexpected, something that got lost in translation.
Please donโt take it personally, laughter is only a human response to surprise. It may not be a pleasant experience to feel laughed at but itโs likely there will be many occasions in your French journey that youโll make a fool of yourself. Trust me, Iโve been there many times in English! So better grow a thicker skin right now and learn to laugh with everybody.
So if โhave a good nightโ is not โbonne nuitโ, then what should you say?

Have a Good Night in French = Bonne Soirรฉe
When wishing someone a good night as a pleasant evening, you should say โBonne soirรฉeโ.
โUne soirรฉeโ is an evening span. You could say:
- Bonne soirรฉe
Have a good evening - Passe/ passez une bonne soirรฉe
Have a good evening - Je te/vous souhaite une bonne soirรฉe
Literally, I wish you to have a good evening
If you are relating your evening, you could say:
- Jโai passรฉ une (trรจs) bonne soirรฉe avec Pierre
I had/enjoyed a (very) good evening with Pierre.
or on the contrary
- Quelle mauvaise soirรฉe ! Jโai vraiment passรฉ une soirรฉe nulle avec Pierreโฆ
What an unpleasant evening! I really had a bad time with Pierre.
Note that in French, โune soirรฉeโ is also a party. Of course the French would associate evening time with partying, right?
When To Use โBonsoirโ in French?
Wait! What about โbonsoirโ? Can you use โbonsoirโ to say โgood nightโ in French?
Yes you can. But โbonsoirโ is more of a greeting, or way to say hello in French when you arrive somewhere in the evening, or sometimes โgoodbyeโ when you leave in the evening.
Originally, of course โbonsoirโ does mean โbon soirโ = โgood eveningโ. But now, itโs rather โflatโ: you are not really expressing the notion of โI wish you a pleasant eveningโ โ youโre just saying โhiโ or โbyeโ 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 ๐
- Bonne soirรฉe = have a pleasant evening ๐ป๐บ๐
- Bonne nuit = enjoy a good night sleep / sleep well ๐ด
