Raymond Keith King (born January 15, 1974) is a retired American professional baseball relief pitcher.

He played in Major League Baseball for the Chicago Cubs, Milwaukee Brewers, Atlanta Braves, St. Louis Cardinals, Colorado Rockies, and Washington Nationals from 1999 to 2008.

That off-season, King was dealt back to Atlanta for infielder Wes Helms and pitcher John Foster.

King joined the Colorado Rockies for the 2006 season after a trade from St. Louis for outfielder Larry Bigbie and second baseman Aaron Miles.

On April 24, King was optioned to Triple-A Columbus, but he refused the assignment and declared free agency, never again to appear in a major league game.

A lefty specialist with a durable arm, King ranked amongst the top ten National League relievers in appearances from 2001 through 2005.

Armed with a late-moving, low 90s fastball and sharp breaking slider, King pitched to the bottom of the strike zone and allowed few home runs.
