William Harris Stewart (born October 18, 1966, in Des Moines, Iowa) is an American jazz drummer.

Stewart met future employer Joe Lovano while still in college (the two played duets in lieu of a drum lesson when Zigmund was away).

After college, Stewart moved to New York, gaining wider recognition in John Scofield's quartet with pianist Michael Eckroth and bassist Ben Street[2] and in a trio with Larry Goldings and Peter Bernstein, which has become the longest-running group Stewart has played with, having begun in 1989 and continuing to this day, performing infrequently.

Another close associate is pianist Kevin Hays, with whom he performs, along with fellow WPC graduate, bassist Doug Weiss.

These custom ride cymbals feature a wider bell with a much lower profile to promote more control while offering a smooth array of rich overtones.
