The incident involved an alleged attack at a nightclub in Tampa in 2017. Brown was accused of punching the club's photographer, who was reportedly taking pictures of him after being told not to.
The photographer suffered a split lip, and later went to hospital and pressed charges.
Pitchfork reports that the charges have now been dropped, according to Hillsborough County court records.
Brown has faced a number of charges in recent years, including one regarding an aggravated rape allegation by a French woman in January this year.
Brown was arrested in Paris, and filed a defamation suit against his accuser several days after the charge.
