Mattapan is a neighborhood in Boston, Massachusetts. Historically a section of neighboring Dorchester, Mattapan became a part of Boston when Dorchester was annexed in 1870. As of the 2010 census, it had a population of 36,480. Like other neighborhoods of the late 19th and early 20th century, Mattapan developed, residentially and commercially, as the railroads and streetcars made downtown Boston increasingly accessible. Predominantly residential, Mattapan is a mix of public housing, small apartment buildings, single-family houses, and two- and three-family houses (known locally as "Three-Deckers" or "Triple-Deckers"). Blue Hill Avenue and Mattapan Square, where Blue Hill Avenue, River Street, and Cummins Highway meet, are the commercial heart of the neighborhood, home to banks, law offices, restaurants, and retail shops. The new Mattapan Branch of the Boston Public library opened 2009, at a cost of more than $4 million.
Mattapan is claimed as the original Native American name for the Dorchester area, though accounts vary whether the phrase meant "a good place to be," or "a good place to sit"  or "an evil, spread about place." 
In the 1960s and 1970s Mattapan went through a major change in the makeup of its population. It shifted from a predominantly Jewish neighborhood to one that is now largely African American and Caribbean American having a population of 37,486 that is over 77% African American and Caribbean American.
The period from 1968 to 1970 made up the most dramatic period of ethnic transition in Boston. According to Levine and Harmon in their book, Death of an American Jewish Community, redlining the area, blockbusting, and fear in neighborhood residents created by real estate agents allegedly brought about panic selling and white flight. The banking consortium Boston Banks Urban Renewal Group (B-BURG) allegedly drove the Jewish community out of Mattapan and are held partially responsible for the ensuing deterioration of the neighborhood, especially along the Blue Hill Avenue corridor. This widely held belief has been disputed, with differences between the Catholic and Jewish communities in Boston being the greater contributing factor. According to Levine and Harmon, the reason behind this orchestrated attack on the community was to lower market values to buy property, sell the housing with federally guaranteed loans at inflated prices to black families who could not afford it, and to get the white community to buy property owned by the banks in the suburbs. Today Mattapan is seeing another major population shift, albeit a natural turn over of housing, as a large number of immigrants from Haiti and other Caribbean countries continue to move in. Mattapan now has the largest Haitian community in Massachusetts, and is also largely made up of African Americans and immigrants from other Caribbean countries..
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.
