ATK Mohun Bagan

Mohun Bagan Super Giant, commonly known as Mohun Bagan, is an Indian professional football club based in Kolkata, West Bengal, founded on 15 August 1889 and considered one of the oldest football clubs in Asia. The club competes in the Indian Super League and is described as the most successful club in Indian football, with a record 267 trophies. Its first notable victory came in the 1911 IFA Shield final against the East Yorkshire Regiment, making it the first all-Indian club to win a championship over a British club, a moment that held significance in India's push for independence.

Known over time as Mohun Bagan Sporting Club, Mohun Bagan Athletic Club, McDowell Mohun Bagan and ATK Mohun Bagan, the club adopted its current name Mohun Bagan Super Giant in 2023 after protests from supporters. The club contests the Kolkata Derby against East Bengal, first played on 8 August 1921, and in the 2024–25 season became the first club to successfully defend the League Shield and achieved the league and cup double for the first time.
