The 1926 South Carolina United States Senate election was held on November 2, 1926, to select the U.S. Senator from the state of South Carolina. Incumbent Democratic Senator Ellison D. Smith won the Democratic primary and was unopposed in the general election to win another six-year term.
Senator Ellison D. Smith was opposed in the Democratic primary by state Representative Edgar Allan Brown of Barnwell County.

There was no opposition to the Democratic candidate in the general election so Smith was elected to another six-year term in the Senate.
