The Patrick J. Kelly Cup goes to the play-off champion of the ECHL. The Kelly Cup has been awarded to teams since 1997. Prior to 1997, the playoff winner was awarded the Riley Cup, named after former American Hockey League President Jack Riley. The current cup is named after Patrick J. Kelly, the league's first commissioner. The cup is loaned to the winning team for one year and is returned at the start of the following year's playoffs. The Kelly Cup Playoffs Most Valuable Player award is also given out as part of the Kelly Cup Championship ceremonies. Nick Vitucci and Dave Gagnon are the only players to win the award on multiple occasions.
16 different teams have won the ECHL Championship, with seven (Alaska, Allen, Cincinnati, Hampton Roads, Idaho, South Carolina, and Toledo) winning multiple times. The Hampton Roads Admirals, the Alaska Aces and the South Carolina Stingrays hold the record for most championships won with three. Current possession of the trophy belongs to the Allen Americans, who won it in 2016 after a six-game victory over the Wheeling Nailers in the Kelly Cup Finals.
The Kelly Cup playoffs is an elimination tournament, consisting of four rounds of a best-of-seven series. The format has changed often throughout the years, but, for the 2016–17 season, the top four point earners from each division qualify. The first two playoff rounds are played within each division, followed by the conference finals (contested between the four division winners), and ending with the Kelly Cup finals (featuring the two conference champions).
