In the United States, a federal judge is a judge who serves on a court established under Article Three of the U.S. Constitution. Often called "Article III judges", federal judges include the chief justice and associate justices of the U.S. Supreme Court, circuit judges of the U.S. Courts of Appeals, district judges of the U.S. District Courts, and judges of the U.S. Court of International Trade.
Federal judges are not elected officials, unlike the president and vice president and U.S. senators and representatives. They are nominated by the president and confirmed by the Senate.
