"Big Bill" Lister (January 5, 1923 – December 1, 2009) was an American honky tonk country music singer. Born Weldon E. Lister, he was nicknamed "Radio's Tallest Singing Cowboy," standing over 6-foot-7 without his cowboy boots and hat.

For several years in the 1950s, he traveled with Hank Williams, Sr., as the opening act for Williams and his "Drifting Cowboys." As a regular performer on the Grand Ole Opry, Lister worked with most of the stars of the day, including Little Jimmy Dickens, String Bean, Minnie Pearl, Del Wood, The Carter Family, and others. He was also a recording artist for both Everstate and Capitol Records. He is probably best known for his ties to Williams' song "There's a Tear in My Beer." Lister recorded the song in the 1950s, after Williams gave him a demo recording. Years later, after Lister's wife found the old demo recording in their attic, Lister gave the recording to Williams' son, Hank Williams, Jr. Junior went on to record an overdubbed version of the song in 1988, in which (late) father and son sang together, some 40 years apart. That recording won a Grammy Award and a Country Music Association (CMA) Award in 1989.
