Masi Marjamäki (born January 16, 1985 in Pori, Finland) is a Finnish ice hockey player who currently plays for Tappara Tampere of the SM-liiga.
Marjamäki, a 6'2" 205 pound left wing, was originally drafted by the Boston Bruins as the 66th overall pick in the 2003 NHL Entry Draft. However, he never came to terms with the Bruins and re-entered the draft in 2005, where he was the 144th overall pick by the New York Islanders.
He played his junior hockey first in his hometown Porin Ässät before moving over the ocean to the Red Deer Rebels and the Moose Jaw Warriors of the WHL before becoming professional in the 2005–2006 season.
After totaling 31 points (9 goals and 22 assists) along with 77 penalty minutes in 75 games for Bridgeport (the Islanders' top affiliate) in the 2005–2006 season, Marjamäki was called up by the big club and made his NHL debut on April 18, 2006 against the Philadelphia Flyers, logging 5 minutes and 17 seconds of glory.
Marjamäki is known for his gritty, physical style of play but is also a good stickhandler who can put points on the board. He has received comparisons to Kirk Maltby of the NHL's Detroit Red Wings.
After a frustrating start to the 2007-2008 AHL season in which Marjamäki was scratched every game, he asked the Islanders to be reassigned to Finland. The Islanders granted his request and he spent the season playing for Ässät.
Marjamäki was signed by Ilves in 2008, and played there until his injury in early 2012-2013 season. He was unable to play at all in the 2013-2014 season, and signed with local rival Tappara for the 2014-2015 season with one year option.
Season 2015-2016 he played one year for Ässät before joining Jokerit to play in KHL. He played total 61 games for Jokerit during one and a half seasons before joining Almtuna IS in Swedish 2nd level.
