According to the U.S. Census Bureau, the town has a total area of 6.8 square miles (17.7 km²), of which, 6.8 square miles (17.6 km²) of it is land and 0.04 square miles (0.1 km²) of it (0.44%) is water.

Brookline borders Newton, Massachusetts (part of Middlesex County, Massachusetts) to the west and Boston (part of Suffolk County, Massachusetts) to the east, north, south, northwest, and southwest; it is therefore non-contiguous with any other part of Norfolk County. Brookline became an exclave in 1873 when the neighboring town of West Roxbury, Massachusetts was annexed by Boston, Massachusetts (and left Norfolk County to join Suffolk County, Massachusetts) and Brookline refused to be annexed by Boston after the Brookline-Boston annexation debate of 1873.
