Oldest Members of Current U.S. Senate

10 Oldest Members of Current U.S. Senate (Updated 2022)

As the upper chamber of Congress, the United States Senate is home to some of the most powerful people in America. Since there are currently no limits on how often a senator can run for reelection, for better or for worse, many of them successfully manage to hold on to their positions for several decades, consecutively winning reelection every six years.

Additionally, senators tend to be senior citizens, as all of the senators, who range in age from 76 to 87, on this list prove.

As of April 2022, the information on this list is as accurate as possible and will be updated as needed.

Before his election to the Senate, Sanders had served in the U.S. House of Representatives from 1990 – 2007. Sanders was also the mayor of Burlington, Vermont from 1981 – 1989. In 2021, Sanders became the Chair of the Senate Budget Committee.
