Alexander Barrett Klots (December 12, 1903 – April 18, 1989) was an American entomologist who specialised in Lepidoptera.
Klots was born in New York City in 1903.
His collection is conserved in the American Museum of Natural History, a smaller part is held by the University of Connecticut.
Two moth species, Neodactria glenni and Neodactria daemonis, were described in the early 21st century using the authority of Bernard Landry and Klots.
