Greg Gilmore (born January 3, 1962) is a French born-American drummer in Seattle, Washington, and co-founder of the recording label First World Music.

After playing in 10 Minute Warning with Duff McKagan (The Fartz, Guns N' Roses), Steve Verwolf, Paul Dana, Bob Groves, and David Garrigues, Gilmore decided to join his friend Duff McKagan when he announced he was leaving Seattle for a new life in L.A, and accompanied him in his early auditions.

Shortly after the success of Guns N' Roses, he moved back to Seattle and in the late 1980s Gilmore was a member of the critically acclaimed, seminal Seattle band Mother Love Bone along with bandmates Andrew Wood (vocals), Bruce Fairweather (guitar), Jeff Ament (bass), and Stone Gossard (guitar).

In the liner notes of Down on the Upside (1996), Soundgarden guitarist Kim Thayil credits Gilmore with "inspiration" for the song "Never the Machine Forever".

1999 saw the release of the eponymous debut album by Radio Chongqing, which Gilmore recorded with bandmates Lesli Dalaba (trumpet) and George Soler (stick).
