A$AP Rocky has one less "F**kin' Problem" ... because the woman he allegedly bitch slapped during one of his shows has dropped her lawsuit.
TMZ broke the story ... Lisa Wade claimed the rapper smacked her in the face at a Philly concert in 2013, and filed filed a civil suit against him.
According to the new court docs though, they've settled the suit, and a judge dismissed it with prejudice -- meaning Wade can't turn around and sue again.
This usually means some money's changed hands -- either to the plaintiff or her lawyers (they tend to like getting paid) -- but details of the settlement are being kept under wraps.
Now they can both pretend this never happened.
