The Office of the District Attorney of Philadelphia is the largest prosecutor's office in Pennsylvania, and one of the largest in the nation.

The District Attorney is an elected-office and terms begin on the first Monday in January following the election. Prior to 1850, the functions of this office were performed by a deputy State Attorney-General.
