Brighton is a former town and current neighborhood of Boston, Massachusetts, United States, located in the northwestern corner of the city. It is named after the English city of Brighton. Initially Brighton was part of Cambridge, and known as "Little Cambridge". Brighton separated from Cambridge in 1807 after a bridge dispute, and was annexed to Boston in 1874. For much of its early history, it was a rural town with a significant commercial center at its eastern end.

The neighborhood of Allston was also formerly part of the town of Brighton, but is now often considered to be separate, leading to the name Allston–Brighton for the combined area. This historic center of Brighton is the Brighton Center Historic District. The Aberdeen section of Brighton was designated as a local architectural conservation district by the Boston Landmarks Commission in 2001.
