Ryan Coiner (born September 7, 1979, in Aliso Viejo, California) is a retired American soccer player who last played for the Columbus Crew of Major League Soccer.

Coiner played college soccer at the University of San Diego from 1999-2002. He was named West Coast Conference Player of the Year twice and second-team All-American twice. He is second all-time in school record books with forty-nine goals scored. During his college years he also played with Orange County Blue Star in the USL Premier Development League, where he played alongside his friend, former German national team coach Juergen Klinsmann.

Upon graduating he traveled to Germany to join Arminia Bielefeld's reserve side. After one season there appearing in twenty games with sixteen goals he was signed by German third-division side 1. FC Union Berlin. With Union Berlin he appeared in thirty-two matches, scoring twelve goals. The next season he was signed by Holstein Kiel where he would appear in thirty-one matches and score ten goals. His success in the German leagues failed to earn him a long-term contract and he was released after the 2005-06 season.

On July 13, 2006, Coiner was signed by the Columbus Crew and almost immediately made his presence felt, notching an assist in his second game with the club, against the Los Angeles Galaxy and nearly scoring the following game against Everton. He was traded to the Chicago Fire at the 2007 MLS SuperDraft, but never played with the club as he retired from the game before the start of the season.
