The Manchester Silkworms were a collegiate summer baseball team located in Manchester, Connecticut playing in the New England Collegiate Baseball League, a collegiate summer baseball league operating in the northeastern United States region of New England.

The team, an expansion franchise formed in 1999 which began play for the 2000 season, was based out of Northwest Park.

In 1838, the Cheney Family started what became the world's largest silk mill, and by the 1920s developed a utopian industrial community.

The mill buildings have undergone restoration and conversion to housing in the recent past.

On Sunday, October 18, 2009, Silkworms founder, owner, and general manager Ed Slegeski announced that he had sold the team to a partnership led by Noah Crane, which moved the team to Laconia, New Hampshire for the 2010 NECBL season.
