Patrick Edward "Bunny" Larkin (March 17, 1882 – August 18, 1948) was an American physician, college football coach, and baseball manager.

The Elmira Morning Telegram wrote, "He was a fast, tricky end, who knew all of the possibilities of the position.

"[11] At Carlisle, he "drilled Warner's Indians to look after Chicago's forward passes and fake plays".

[12] He turned down the opportunity to coach at Georgetown for the 1908 season despite strong support from the school's alumni and students.

[14][15] Larkin worked for many years as the club physician for the Washington Senators baseball team.

[19] During the 1913 season, Warner, a long-time friend, lent his assistant and former Carlisle star Albert Exendine to coach the Georgetown football team in its final games as a favor to Larkin.
