Jamie Foxx was allegedly involved in a fight in the dining room of Mr. Chow Friday night ... and he may have been injured, TMZ has learned.

Law enforcement sources tell us ... police were called to the popular, high-end Beverly Hills restaurant around 10 PM on the report of a fight inside.

For the moment, details are murky ... but we are told by police sources that Jamie was involved in the alleged altercation -- however, he was gone by the time police arrived.
