This is a list of roundabouts in the state of Massachusetts in the United States. Intersections that are called traffic circles or roundabouts in the rest of the US are referred to as "rotaries" in Massachusetts, as well as other parts of New England including parts of Connecticut, New Hampshire, Maine & Vermont. In 2017 the MassDOT announced that it was eliminating rotaries in favor of Roundabouts. In 2020 it issued guidance on the design and planning for roundabouts.
