John Shannon Munn (6 June 1880 – 24 February 1918) was a prominent early-20th-century Newfoundlander. The step-son of Sir Edgar Bowring, he rose to become managing director of Bowring Brothers, but died in the wreck of the SS Florizel in 1918, along with his three-year-old daughter, Betty. Munn had also been a talented cricketer in his youth, and is one of the few Newfoundlanders to play at first-class level, having played in England for Oxford University.
