The United States District Court for the District of Massachusetts (in case citations, D. Mass.) is the federal district court whose territorial jurisdiction is the Commonwealth of Massachusetts, United States.[1] The first court session was held in Boston in 1789. The second term was held in Salem in 1790 and court session locations alternated between the two cities until 1813. That year, Boston became the court's permanent home. A western division was opened in Springfield in 1979 and a central division was opened in Worcester in 1987. The court's main building is the John Joseph Moakley Federal Courthouse on Fan Pier in South Boston.
Appeals from the District of Massachusetts are heard by the United States Court of Appeals for the First Circuit, also located in the Moakley courthouse (except for patent claims and claims against the U.S. government under the Tucker Act, which are appealed to the Federal Circuit).

The Eastern Division, covering Barnstable, Bristol, Dukes, Essex, Middlesex, Nantucket, Norfolk, Plymouth, and Suffolk counties. Cases filed in the Eastern Division are heard in Boston.
The Central Division, covering Worcester county. Cases filed in the Central Division are heard in Worcester.
The Western Division, covering Berkshire, Franklin, Hampden, and Hampshire counties. Cases filed in the Western Division are heard in Springfield.
