This is a list of all roster changes that occurred prior to the 2015 Indian Super League season.

Player regulations for 2015
For the 2015 season, the controlling body for the Indian Super League, Football Sports Development, have decided to introduce a salary cap which shall be set at Rs. 20 crores after a meeting that took place on 9 March 2015. Also at the meeting, the organization revealed other roster rules for the 2015 season which were:
 * Marquee player: Each team will be required to sign one marquee player for the 2015 season. The marquee player can be the same marquee from last season but teams are also allowed to sign a new one.
 * International players: Each team will be allowed to retain between one and five foreign players from the previous season and they're allowed to sign new foreigners without an international players draft.
 * Domestic players: Each team will be allowed to retain between one and six Indian domestic players. Indian players who are not retained by their teams will be allowed to freely sign for another Indian Super League team till May 2015. If the players are still without a team by May 2015 then they will be listed as an option in the domestic draft in June.

It was also revealed during the meeting that each team may have a minimum of 22 players in their squad, with the addition of two developmental players. This would mean that each team should have a minimum of one marquee player, eight international players, and thirteen domestic Indian players in which two must be developmental players. Maximum, each team may contain 25 players, with two of the addition three players being allowed to be foreign.
