The Massachusetts Appeals Court is the intermediate appellate court of Massachusetts. It was created in 1972 as a court of general appellate jurisdiction. The court is located at the John Adams Courthouse at Pemberton Square in Boston, the same building which houses the Supreme Judicial Court and the Social Law Library.

Pemberton Square in the Government Center area of Boston, Massachusetts, was developed by P.T. Jackson in the 1830s as an architecturally uniform mixed-use enclave surrounding a small park. In the mid-19th century both private residences and businesses dwelt there. The construction in 1885 of the massive John Adams Courthouse changed the scale and character of the square, as did the Center Plaza building in the 1960s.
