Lloyd Estel Copas (July 15, 1913 – March 5, 1963), known by his stage name Cowboy Copas, was an American country music singer popular from the 1940s until his death in the 1963 plane crash that also killed country stars Patsy Cline and Hawkshaw Hawkins.

Copas was born in 1913 in Jefferson Township in Adams County, Ohio. He began performing locally at age 14, and appeared on WLW-AM and WKRC-AM in Cincinnati during the 1930s. In 1940 he moved to Knoxville, Tennessee, where he performed on WNOX-AM with his band, the Gold Star Rangers.

In 1943, Copas achieved national fame when he replaced Eddy Arnold as a vocalist in the Pee Wee King band and began performing on the Grand Ole Opry. His first solo single, "Filipino Baby," released by King Records in 1946, hit number four on the Billboard country chart and sparked the most successful period of his career.
