The 2013 Kelly Cup Playoffs of the ECHL started on April 5, 2013, following the end of the 2012–13 ECHL regular season. The playoff format changed from that of the 2012 postseason; 16 teams qualified for the playoffs, the top eight teams from both the Western Conference and the Eastern Conference. First-round series were scheduled as best-of-seven, where in prior years they were best-of-five.
