2009-10 IHL season

The 2009–10 IHL season is the 3rd season of the International Hockey League (IHL).

Departures
Prior to the 2009-10 season, the Kalamazoo Wings, announced their intentions to leave the league and a few weeks later, Kalamazoo joined the ECHL.

Additions
The IHL added one team for the 2009-10 season in Dayton, Ohio and welcomed back a franchise in Moline, Illinois.

The Dayton Gems, based in the Dayton, Ohio suburb of Trotwood, Ohio, will compete at Hara Arena. Dayton was home to the Dayton Bombers of the ECHL from 1991–2009, but the team relinquished their membership following a failed season ticket drive to return in for the 2010-11 season. The IHL Dayton franchise takes its name from the original Dayton Gems who competed in the original IHL.

A second incarnation of the Quad City Mallards, based in Moline, Illinois, will compete in the iWireless Center. The original Quad City Mallards, along with the Rockford IceHogs, left the United Hockey League (the predecessor to the new IHL) following the 2006-07 season and joined the American Hockey League. After two seasons in the league, the Quad City AHL team was moved to Abbotsford, British Columbia and Quad City was welcomed into IHL. Quad City has signed affiliation agreements with the Philadelphia Flyers of the National Hockey League and the Adirondack Phantoms of the American Hockey League. Quad City is the only team in the IHL with an affiliation agreement with an NHL club.
