Y.M.C.A. est une chanson disco de 1978 du groupe Village People, en référence au Young Men's Christian Association (Union Chrétienne de Jeunes Gens), un mouvement de jeunesse chrétien, exclusivement masculin jusque dans les années 1970, fondé en 1844 par George Williams (1821-1905).
Elle a été composée par Jacques Morali, Henri Belolo (producteurs français) et Victor Willis (le "policier") et intégrée à l'album Cruisin'. Aux États-Unis, la chanson est distribuée par la maison de disques Casablanca et elle se classe n°2 disco.
La chanson est rechantée par Ray Simpson (qui a remplacé Willis) dans le film où joue le groupe, Can't stop the music (1980) et c'est là qu'apparaît une chorégraphie avec les bras des danseurs tendus dans les airs qui imitent successivement les quatre lettres du titre.
Parmi les reprises, une version punk par le groupe basque Skunk, une version merengue/rap par Papi Sanchez, celle des Schtroumpfs, adaptée en français, Moi j'aime danser, celle de Pigloo, Moi j'aime skier, et celle de Francky Vincent Moi j'aime scier, en 2010. Citons également la parodie Chez les pédés des Bidochons sur l'album Saturday Night Bidochons. On retrouve aussi une reprise au Japon par Razor Ramon "Hard Gay" dont le titre est Young Man.
Également échantillonnée en 1998 par Diva Surprise (feat. Georgia Jones) sur le titre On The Top Of The World.
George Lam a chanté cette chanson en Cantonais.

[Verse 1]
Young man, there's no need to feel down
I said, young man, pick yourself off the ground
I said, young man, cause you're in a new town
There's no need to be unhappy
Young man, there's a place you can go
I said, young man, when you're short on your dough
You can stay there, and I'm sure you will find
Many ways to have a good time

[Hook]
It's fun to stay at the Y.M.C.A
It's fun to stay at the Y.M.C.A
They have everything for you men to enjoy
You can hang out with all the boys
It's fun to stay at the Y.M.C.A
It's fun to stay at the Y.M.C.A
You can get yourself clean, you can have a good meal
You can do whatever you feel

[Verse 2]
Young man, are you listening to me?
I said, young man, what do you want to be?
I said, young man, you can make real your dreams
But you got to know this one thing
No man does it all by himself
I said, young man, put your pride on the shelf
And just go there, to the Y.M.C.A
I'm sure they can help you today

[Hook]
It's fun to stay at the Y.M.C.A
It's fun to stay at the Y.M.C.A
They have everything for you men to enjoy
You can hang out with all the boys
It's fun to stay at the Y.M.C.A
It's fun to stay at the Y.M.C.A
You can get yourself clean, you can have a good meal
You can do whatever you feel

[Verse 3]
Young man, I was once in your shoes
I said, I was down and out with the blues
I felt no man cared if I were alive
I felt the whole world was so jive
That's when someone came up to me
And said, young man, take a walk up the street
There's a place there called the Y.M.C.A
They can start you back on your way

[Outro]
It's fun to stay at the Y.M.C.A
It's fun to stay at the Y.M.C.A
They have everything for you men to enjoy
You can hang out with all the boys
Y.M.C.A....It's fun to stay at the Y.M.C.A
Young man, young man, there's no need to feel down
Young man, young man, get yourself off the ground
Y.M.C.A....you'll find it at the Y.M.C.A
No man, no man does it all by himself
Young man, young man, put your pride on the shelf
Y.M.C.A....just go to the Y.M.C.A
Young man, young man, are you listening to me?
Young man, young man, what do you wanna be?
Y.M.C.A....you find in the Y.M.C.A....
No man, no man does it all by himself
Young man, young man, put your pride on the shelf
Y.M.C.A....just go to the Y.M.C.A
Young man, young man I was watching your shoes
Young man, young I was down with the blues
