Katt Williams is sitting in a Georgia jail cell after getting busted for hitting a store clerk ... TMZ has learned.

Police tell us Katt was arrested Monday at a pool supply store in Gainesville, GA. Officers say Katt had a verbal altercation with an employee and it escalated when he threw an object ... and then punched the employee.

Katt, who's had his fair share of arrests, assumed the position -- cops say he was on the ground with his hands behind his back ... ready to be cuffed when they arrived.

Katt was released on $5,000 bail.
