Tommy McClennan (January 4, 1905[1] – May 9, 1961) was an American Delta blues singer and guitarist.

[4] His voice is heard in the background on Petway's recording of "Boogie Woogie Woman" (1942).

[6] McClennan's "I'm a Guitar King" was included in the 1959 collection The Country Blues, issued by Folkways Records.

"You just make the chords and change when you feel like changing"[5] John Fahey's "Screaming and Hollerin' the Blues" contains an interview with Booker Miller, a contemporary of Charlie Patton's, in which Miller mentioned someone who is most likely Tommy McClennan, though Miller did not know his name: "... and I saw another fella he put some records out, they (him and Willie Brown) be together, but he be by himself when I see him, they called him "Sugar"...

Bob Dylan covered Tommy McClennan's track, "Highway 51" (which was written by Curtis Jones), on his self-titled debut album in 1962.
