Adam Richard Deadmarsh (born May 10, 1975) is a Canadian-born American former professional ice hockey player who played in the NHL with the Quebec Nordiques, Colorado Avalanche, and Los Angeles Kings.

Deadmarsh was later a video coordinator and assistant coach with the Avalanche,[1] before concussion issues forced him to step down after the 2011–12 season, nine years after his playing career ended for the same reason.

[2][3] He was traded to the Los Angeles Kings on February 21, 2001, along with Aaron Miller, a player to be named later (Jared Aulin), and Colorado's first round pick in the 2001 NHL Entry Draft (Dave Steckel) for Rob Blake and Steve Reinprecht.

He was honored on March 20, 2006, before a game between the Avalanche and Kings at Staples Center in downtown Los Angeles, California, for his dedication to both teams.

[7] After only serving 1 season as an Assistant Coach with Colorado, Adam ultimately resigned from his position behind the bench due to concussion issues on June 7, 2012, and took on a new role with the organization working in their player development office.
