List of members of the United States Congress by brevity of service

This is a list of United States congresspersons by brevity of service. It includes representatives and senators who have served less than six years in the Senate or less than two years in the House, not counting currently serving members. This list excludes members whose term ended with 73rd United States Congress that served the entirety of that term, which due to the Twentieth Amendment to the United States Constitution, only lasted from March 4, 1933, to January 3, 1935, and inaugural holders of Class 1 and Class 2 Senate seats that served the entirety of the first term, due to the initial terms being only 2 and 4 years long respectively, as the Senate classes were staggered so that a third of the seats would be up every two years.
