Youngest U.S. Congressmen Ever

10 Youngest U.S. Congressmen Ever

The minimum required age for a Congressman is only 25 years old and everyone on this list was elected just before their 25th birthday. Most of them were 25 by the time they actually took their congressional seat. Because sources differ on his date of birth, the youngest congressman ever may have been as young as 22 years old. Some of the young congressmen on this list had very brief political careers, while others stayed in politics for decades.
