Keith Edward Acton (born April 15, 1958) is a Canadian former professional ice hockey centre who played 15 seasons in the National Hockey League (NHL), with the Montreal Canadiens, Minnesota North Stars, Edmonton Oilers, Philadelphia Flyers, Washington Capitals and New York Islanders between 1980 and 1994.

On October 28, 1983, Acton was traded alongside teammate Mark Napier to the Minnesota North Stars for Bobby Smith.

Acton was a healthy scratch through the first two rounds and remained in the press box through the first three games of the conference final against the Detroit Red Wings.

However, with the Oilers' coaching staff looking for more speed on their fourth line, Acton was inserted into the lineup for game four and he paid immediate dividends, scoring the series-clinching goal.

His clutch play continued in the Stanley Cup Finals when he ended game one against the Boston Bruins by tipping a Steve Smith point shot for the game-winning goal.

Despite his playoff heroics, it still proved difficult to carve out a place on the Oilers' deep roster and late in the 1988-89 season, on February 7, 1989, Acton was traded to the Philadelphia Flyers for Dave Brown.

After retiring from playing, Acton would become the assistant coach of multiple NHL teams including the Philadelphia Flyers, New York Rangers, Toronto Maple Leafs, Columbus Blue Jackets, and Edmonton Oilers.
