Crazy scene on the streets of Atlanta ... a bunch of men got into a huge fight in full view of security guards ... and it's all on video.

Ya gotta see the footage ... it's complete chaos outside a business as a well-dressed group of guys brawl ... fists and feet are flying and whizzing all over the place.

Sources tell TMZ ... the fight happened outside The Interlock in Atlanta a little after 11 PM Sunday night ... with security breaking up the fight.

We're told police were NOT called and everyone involved in the brawl went their separate ways after the fight died down.

We've seen lots of fights at the Atlanta airport over the years ... but now things are spilling into the streets.

Welcome to Atlanta where the players play fight.
