MetroWest is a cluster of cities and towns lying west of Boston and east of Worcester, in the U.S. state of Massachusetts. The name was coined in the 1980s by a local newspaper.
While regional definitions vary, the MetroWest Economic Research Center at Framingham State University defines MetroWest as the nine towns of Ashland, Framingham, Holliston, Hopkinton, Natick, Sherborn, Southborough, Sudbury, and Wayland, representing a total population of approximately 184,000. With the exception of Southborough, in Worcester County, these towns are part of Middlesex County.
