Mike Robert Marson (born July 24, 1955, in Scarborough, Ontario, ) is a retired Canadian professional ice hockey left winger who played five seasons in the National Hockey League for the Washington Capitals and the Los Angeles Kings.
Marson was drafted in the 2nd Round, 19th overall by the Washington Capitals in the 1974 NHL Entry Draft. Marson signed a five-year contract with the Capitals and became the second black player to play in the NHL. Former Boston Bruin Willie O'Ree broke the NHL's colour barrier in 1957–58.
He played a full season with the Capitals in 1974-75 and scored a respectable 16 goals. But there was too much pressure being put on the young rookie by the expansion team and Marson could not handle it. His play steadily went down and he started spending more time in the minor pros. A trade to the Los Angeles Kings in 1979 did little to help his career and he retired in 1980.
In his NHL career Marson played in 196 games and scored 24 goals and 24 assists.
