Adrien Broner -- Praised By Homeless Org ... For $1,000 GIveaway

Adrian Broner is an INSPIRATION ... so says a rep for the National Organization For the Homeless who tells TMZ Sports the boxing champ should be applauded for giving $1k to an unsuspecting homeless man earlier this week.

The footage went viral almost immediately -- showing Broner rolling up to a homeless man on a street corner and surprising him with $1k in cash. The man's reaction was super emotional.

Some people have criticized the move as a shameless publicity stunt -- but N.C.F.H. says other ballers should follow Broner's lead.

"We think what he did was really cool, and we hope it will inspire anyone who has extra money to do the same," a rep tell us.
