Rockette Morton (born Mark Boston; July 14, 1949[1][deprecated source] in Salem, Illinois) is an American musician, best known as a bassist and guitarist for Captain Beefheart and the Magic Band in the 1960s and 1970s.

Morton played on five of Beefheart's albums: Trout Mask Replica (produced by Frank Zappa in 1969), Lick My Decals Off Baby (1970), The Spotlight Kid (1972), Clear Spot (1972) and Unconditionally Guaranteed (1974).

These tensions led to a split in 1974, when Rockette Morton left to form Mallard with bandmates John French, Bill Harkleroad, and Art Tripp.

Prior to the album's release he was featured in an article in the music magazine Stomp & Stammer (October 2002), titled "The Ring of Rockette Morton", in which he self-identified as "a space nut" and being "pro-space".
