Glenn "Mooch" Myernick (December 29, 1954 in Trenton, New Jersey – October 9, 2006 in Thornton, Colorado) was an American soccer player and coach.
When Portland folded following the 1982 season, the Tampa Bay Rowdies selected Myernick in the dispersal draft.
Myernick spent one season, 1979–1980, with the Wichita Wings of Major Indoor Soccer League.
After the highly successful Quarterfinal run made by the United States, Myernick coached the U.S. Men's U-23 Soccer team as they attempted (unsuccessfully) to qualify for the 2004 Olympic Tournament.
Myernick served as the head coach of the Colorado Rapids of Major League Soccer from 1997 to 2000, leading them into the playoffs in each of the four seasons.
The Rapids made it all the way to the MLS Cup final in his first year at the helm, coming up short 2–1 to D.C. United at RFK Stadium.
The team also advanced to the Lamar Hunt U.S. Open Cup final in 1999, losing 2–0 to the Rochester Raging Rhinos.
On April 8, 2015, Myernick was elected to the National Soccer Hall of Fame along with Sigi Schmid and Kasey Keller.
