Dirk Von Hayhurst (born March 24, 1981) is an American author and broadcaster, and formerly a professional baseball pitcher.

Hayhurst was claimed off waivers by the Toronto Blue Jays on October 6, 2008, but was released four months later before the season started, and re-signed to a minor league deal.

Prior to the 2011 season, Hayhurst signed a minor league contract with the Tampa Bay Rays with an invitation to spring training.

On June 8, 2012, Hayhurst announced that he signed with Rogers owned Sportsnet 590 The Fan to co-host Baseball Central alongside Sam Cosentino, starting July 3, 2012.
