Thom Mooney (born 5 January 1948, Altoona, Pennsylvania) is an American drummer.
Strongly influenced by the British invasion during the sixties, he was a founding member of the East Coast rock group Nazz, along with guitarist Todd Rundgren, who later went on to have a successful solo career. With the release of the first album Nazz (the name derived from an old jazz expression as well as the Yardbirds hit "The Nazz Are Blue"), his group had a larger than life live show, touring with the then-nascent group Spirit, with a huge guitar-driven sound that was firmly propelled by Mooney's wildly energetic drumming style. Reviews were more than enthusiastic, but the group's demise, shortly after their return to the recording studio, was the result of growing pains and perhaps too much hype. Mooney went on to assist in the release of the second album Nazz Nazz, and a posthumous third album Nazz III, but then worked to become one of the most active rock drummers on the burgeoning 70s scene, eventually working as musical director and drummer for Rita Coolidge, as well as session work and writing with Men at Work's Colin Hay, John Hiatt, tours with Roger McGuinn, and many others. As well as Nazz, he has drummed with Fuse, Paris (with Bob Welch), the Curtis Brothers and Tattoo (with Wally Bryson). At present, Mooney lives on the West Coast, and still active in music.
