Dale Leon Bumpers (born 12 August 1925) was a Democratic member of the United States Senate from the State of Arkansas, and was the governor of Arkansas from 1971 to 1975.

Dale Bumpers was born in Charleston, Arkansas. He attended public schools and the University of Arkansas. He served in the United States Marine Corps from 1943 to 1946, during World War II. Bumpers graduated from Northwestern University Law School in 1951 and was admitted to the Arkansas bar in 1952. He started practicing law in his hometown in that same year and served as Charleston city attorney from 1952 to 1970. He served as special justice of the Arkansas Supreme Court in 1968.

The previous Democratic governor had been defeated by a Republican reformer, Winthrop Rockefeller. Bumpers ran for election against Rockefeller in 1970 as a new type of Democrat who would bring reform to the Democratic Party. Bumpers defeated Rockefeller and ushered in a new era of youthful reform-minded governors. Bumpers served as governor from 1971 to 1975, when he was elected to the United States Senate. He served in the Senate from 1975 to 1999, and was chairman of the Committee on Small Business and Entrepreneurship. Bumpers was known for his oratorial skills.

Bumpers and his wife Betty were both known for their dedication to the cause of childhood immunization.

Bumpers was never a particularly close political ally of President Bill Clinton but gave an impassioned speech in defense of him during Clinton's impeachment trial.
