Diamond Harbour FC

Diamond Harbour Football Club was established in 2020 and approved by the Indian Football Association (IFA) in 2022 to participate in the Calcutta Football League (CFL) First Division, the third tier of the state league structure. Spanish coach Kibu Vicuña, previously associated with Mohun Bagan and Kerala Blasters, was appointed as the club's first head coach. In 2023, the Indian Football Association introduced a new format by merging the CFL Premier Divisions A and B into a single competition. DHFC was placed in Group I and qualified for the Super Six stage of the tournament. Later in the year, the club was nominated to represent West Bengal in the inaugural season of the I-League 3, the new fourth tier in the Indian league system. In 2024, Diamond Harbour FC took part in the Sikkim Gold Cup held in Gangtok, reflecting its growing participation in national-level competitions. The club won the I-League 2 and was promoted to the I-League in the same year. Diamond Harbour made their Durand Cup debut in 2025, where they reached the final by beating Indian Super League clubs Jamshedpur FC and East Bengal FC. However, they lost the final 6–1 to NorthEast United FC and finished runners up. Diamond Harbour won the 2025–26 Indian Football League and was promoted to the 2026–27 Indian Super League, until withdrawal due to financial reasons.
