John McDonald Mowat (February 17, 1872 – October 7, 1916) was a lawyer and politician in Ontario, Canada. He served as mayor of Kingston from 1906 to 1907.

He ran unsuccessfully for the Kingston seat in the Canadian House of Commons in 1911, losing to William Folger Nickle. He went overseas as a Major with a Vancouver regiment during World War I and was killed in action at the age of 44.

His nephew Angus McGill Mowat also served in World War I, and his great-nephew is Canadian author Farley Mowat.
