Stanley B. Mulaik (September 30, 1902 – March 17, 1995) was an American zoologist and educator.
He received a bachelor's degree in science education and worked as a school teacher for several years until commencing his PhD studies at the University of Utah in 1939.
He was appointed as an assistant (and later associate) professor at the University of Utah, where he taught courses in nature study, conservation, the teaching of biology, museum techniques, and arthropod anatomy.
He was jointly or separately involved in describing over 200 new species of spiders, isopods, scorpions and mites.
The Mulaiks are commemorated in the names of several organisms, including nine spider species from Texas.
