The 1970 United States Senate election in Florida was held on November 3, 1970. Incumbent Democratic U.S. Senator Spessard Holland decided to retire instead of seeking a fifth term. During the Democratic primary, former Governor C. Farris Bryant and State Senator Lawton Chiles advanced to a run-off, having received more votes than Speaker of the Florida House of Representatives Frederick H. Schultz, attorney Alcee Hastings, and State Representative Joel T. Daves III. Chiles soundly defeated Bryant in the run-off election, scoring a major upset due to his comparatively small name recognition prior to the election. To acquire name recognition and media coverage, Chiles walked about 1,003 miles (1,614 km) across the state of Florida and was given the nickname "Walkin' Lawton".

The Republican primary exposed an in-party feud between Governor Claude R. Kirk Jr. and U.S. Representative William C. Cramer. In the election, Cramer handily defeated G. Harrold Carswell and body shop owner George Balmer; the former was a Fifth Circuit Court of Appeals judge favored by Kirk and had been rejected as a Supreme Court of the United States nominee a few months prior to the primary. Chiles won the election by a relatively small margin of 7.8%, receiving 902,438 votes against Cramer's 772,817 votes.
