The Commonwealth of Independent States Cup (Russian: Кубок чемпионов Содружества, Кубок Содружества, Кубок чемпионов содружества стран СНГ и Балтии) is a defunct annual regional association football tournament, recognized by FIFA.
The tournament was initially established for football clubs of the former Soviet Union republics in 1993 (a year later since the collapse). On several occasions, some national football organizations of the former Soviet republics as well as individual clubs refused participation in the tournament for different reasons. Usually the invitation was sent to the best clubs of the Commonwealth of Independent States member states, as well as Estonia, Latvia, Lithuania, i.e. either a champion or a runner-up, while in the later editions the Cup (before 2012) saw participation of clubs from Serbia and Finland.
In 2012, the CIS Cup became a competition of national youth teams. Previously only the Russia under-21 team competed in the competition.
The competition was disestablished in 2016.
The Commonwealth of Independent States Cup started in 1993 as an open tournament to champions from the USSR successor states (The Commonwealth of Independent States, and well as Estonia, Latvia and Lithuania).
Ukraine boycotted the first two competitions, but joined in 1995.
In 1995-2006 the Russia national under-21 football team participated in the tournament as the 16th team, but in 2007 and 2008 Serbia replaced it as the 17th nation sending a team to play in it, and became the first non-former Soviet Union nation participating in the tournament. Unlike the rest of the states, who send their latest champions to play in the tournament, Serbia has sent OFK Beograd to play in the tournament.
