Middlesex County is one of two U.S. counties (along with Santa Clara County, CA) to be amongst the top 25 counties with the highest household income and the 25 most populated counties. Middlesex County is included in the Census Bureau's Boston–Cambridge–Newton, MA–NH Metropolitan Statistical Area. It is bounded southeast by the Charles River, and drained by the Merrimack, Nashua, and Concord rivers, and other streams. The MetroWest region comprises much of the southern portion of the county.

Middlesex County is home to the Middlesex County Volunteers, a fife and drum corps that plays music from the 17th, 18th, 19th and 20th centuries. Founded in 1982 at the end of the United States Bicentennial celebration, the group performs extensively throughout New England. They have also performed at the Boston Pops, throughout the British Isles and Western Europe, and at the Edinburgh Military Tattoo's Salute to Australia in Sydney, Australia.
