The Colonial Athletic League was a high school athletic conference located in District 2 of the Massachusetts Interscholastic Athletic Association. The league was formed in 1976 by a handful of vocational schools in central Massachusetts, and grew to nine vocational and charter schools across the Worcester and Middlesex Counties.

The league would fold in 2025 after merging with the Central Massachusetts Conference, Dual Valley Conference, Inter-High League, and the Southern Worcester County League to form the Central Massachusetts Athletic Conference.
