Douglas Allen "Diesel" Mohns (December 13, 1933 – February 7, 2014) was a professional ice hockey player who played 22 seasons in the National Hockey League from 1953–54 until 1974–75. Mohns twice won the most coveted prize in junior hockey, the Memorial Cup. He played on the 1951 and 1953 Barrie Flyers teams.
Mohns played 1390 career NHL games, scoring 248 goals and 462 assists for 710 points, as well as compiling 1250 penalty minutes. Mohns played both forward and defence in his career. Mohns joined the Boston Bruins in 1953, where he became a versatile cornerstone of that franchise for 11 seasons. An early slapshot expert, he combined skating speed and breakout passing skills with rugged reliability. Mohns starred with Bruins captain and blueline Stalwart Fern Flaman on defence and longtime teammate, smooth Centre Don McKenney on offence, during the Bruins' halcyon years of the late 1950s. Mohns became an alternate captain with the Boston Bruins in 1960. He remained a team pillar during the difficult reconstruction period of the early 1960s.
