The party leadership of the United States Senate refers to the officials elected by the Senate Democratic Caucus and the Senate Republican Conference to manage the affairs of each party in the Senate. Each party is led by a floor leader who directs the legislative agenda of their caucus in the Senate, and who is augmented by an Assistant Leader or Whip, and several other officials who work together to manage the floor schedule of legislation, enforce party discipline, and oversee efforts to maintain and grow the party's seats in the Senate.
