William C. Cobham (born May 16, 1944 in Panama), is a Panamanian American jazz drummer, composer and bandleader, who has called Switzerland home since the late 1970s.

Coming to prominence in the late 1960s and early 1970s with trumpeter Miles Davis and then with Mahavishnu Orchestra, Cobham is, in the words of Steve Huey, "generally acclaimed as fusion's greatest drummer with an influential style that combines explosive power and exacting precision.[1]
