Founded in 1998 by a group of international soccer enthusiasts, including current Chairman Ian Woodcock, Manhattan Celtic has emerged as a dominant force in New York City's soccer landscape. The club's journey began in the Cosmopolitan Soccer League, where it steadily climbed the ranks, culminating in a well-deserved promotion to the top division.

As the club's success grew, so did its membership. The addition of Over-30 and Over-40 men's teams, as well as a women's team, further solidified Manhattan Celtic's position as a comprehensive soccer club.

In 2021, the club achieved a major milestone by securing promotion to the Eastern Premier Soccer League (EPSL). This success led to the restructuring of the reserve team into two divisions: D2 Firsts and Reserves.

Building on this momentum, the CSL first team earned promotion back to D1 in 2023. The club's commitment to fostering talent and providing opportunities for players of all ages is evident in the recent revival of the Celtic Bhoys, who will compete in CSL D4.

With five teams across four divisions, Manhattan Celtic is poised to continue its growth and success, leaving an enduring legacy on the New York soccer scene.
