The 2015 Malaysia Cup began on August with a preliminary round.
Pahang were the defending champions, having beaten Johor Darul Takzim on a penalty shootout 5–3 in last season's final, but they were eliminated by the eventual winner, Selangor, in the semi-finals.
The remaining two teams from 2015 Malaysia Super League and the team who finished 5th and 6th place in the 2015 Malaysia Premier League competed in the playoffs for the remaining 2 spots.
The draw for the 2015 Malaysia Cup was held on 27 August 2015 at the Hilton Petaling Jaya with the participating team coaches and captains in attendance.
In the knockout phase, teams played against each other over two legs on a home-and-away basis, except for the one-match final.
