Route 8A refers to two separate north–south state highways in western Massachusetts in the United States. Both sections are marked as "Route 8A" on guide signs and reassurance markers. In official documentation, MassHighway denotes one highway as 8A-U, and the other as 8A-L, for "upper" and "lower", respectively.

Unlike Route 2A and other suffixed Massachusetts state highways with multiple sections, both 8A-U and 8A-L bypass the same portion of Route 8, possibly causing confusion for travelers unfamiliar with the area.
