Star Smashers of the Galaxy Rangers is a 1973 comic science fiction novel by American writer Harry Harrison. It is a parody of the space opera genre and in particular, the Lensman and Skylark series of E. E. "Doc" Smith. The main characters are homages to Tom Swift Jr. and his buddy, Bud Barclay. It also includes a homage to Larry Niven's Ringworld (1970).
