List of United States Senators from Delaware

This is a listing of the United States Senators from Delaware. They were originally elected by the Delaware General Assembly for designated six-year terms beginning March 4. Frequently portions of the term would remain only upon a senator's death or resignation. From 1914 the senators were popularly elected on the first Tuesday after November 1, and starting 1935 the beginning of their term is January 3, not March 4.
