Wilbert Lee "Pappy" O'Daniel (March 11, 1890 – May 11, 1969) was an American Democratic Party politician from Texas, who came to prominence by hosting a popular radio program. Known for his populist appeal and support of Texas's business community, O'Daniel served as the 34th governor of Texas (1939–1941) and later its junior United States senator (1941–1949). O'Daniel chose not to run for reelection to the Senate in 1948 and was succeeded by his 1941 Democratic primary opponent and future U.S. president Lyndon B. Johnson.
