The United States Senate Committee on the Judiciary (informally Senate Judiciary Committee) is a standing committee of the United States Senate, the upper house of the United States Congress. The Judiciary Committee is charged with conducting hearings prior to the Congressional confirmation of U.S. Supreme Court justices, court of appeals judges, and district court judges. In recent years, this role has made the committee increasingly a point of contention, with numerous party-line votes and standoffs over which judges should be approved. The committee also has a broad jurisdiction over matters relating to federal criminal law.

The committee, along with the Finance and Foreign Relations committees, is one of the oldest in the Senate, having been initially created in 1816.
