Mattapan is the original Native American name for the Dorchester area and meant "a good place to be," or "a good place to sit."
The Mattapan-Ashmont trolley line of the MBTA serves Mattapan as well as several bus routes. The Fairmount Line of the MBTA Commuter Rail also serves Mattapan at Morton Street, providing service to downtown Boston and the suburbs. In the near future an additional station at Blue Hill Avenue will be added. Plans for the reconstruction of Mattapan station have been approved and construction began in late 2006.
