Timothy A Stewart (born 30 September 1952) is a molecular biologist. He graduated from the University of Otago (BScHons, PhD.)

He was a pioneer in the technique of transferring recombinant genes to mice (transgenic mice) and in 1988 he and Philip Leder were granted a patent on a genetically engineered mammal. This "oncomouse" patent was the first to be issued covering a higher life form.[1]
