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.

O'Daniel chose not to run for reelection to the Senate in 1948 and was succeeded by future U.S. president Lyndon B. Johnson.

O'Daniel attended local schools and graduated from the two-year program at Salt City Business College in Hutchinson, Kansas.

To that end, he wrote songs, sang, and hired a group of musicians to form an old timey band to back his vocals.

Originally called the Light Crust Doughboys, notable musicians such as Bob Wills got their start with O'Daniel.

O'Daniel also hosted a regular noontime radio show heard statewide, which gave him his nickname after a catchphrase used frequently on air – "pass the biscuits, Pappy" – and propelled him into the public spotlight.

As a national magazine reporter wrote at the time: "At twelve-thirty sharp each day, a fifteen-minute silence reigned in the state of Texas, broken only by mountain music, and the dulcet voice of W. Lee O'Daniel."

O'Daniel ran for governor in 1956 and 1958 and claimed that the Brown v. Board of Education decision was part of a Communist conspiracy.
