Route 20A is a state highway located entirely within Springfield, Massachusetts, United States. The route, an alternate route of U.S. Route 20, parallels the section of U.S. 20 concurrent with Interstate 291. The western terminus is at U.S. 20 and Interstate 91 in downtown Springfield east of where U.S. 20 crosses the Connecticut River on the North End Bridge. The eastern terminus is at U.S. 20 and I-291 northeast of the city.

This alignment provides an alternate to Interstate 291, which overlaps US 20 for much of its length, but was originally an alternate to old US 20, which ran down State Street and Boston Road. This route was therefore never part of US 20, but has served as an alternate to two separate routes.
