North Chelmsford, also known by some locals as "NoCho," is an unincorporated village in the town of Chelmsford, Massachusetts, United States. Although North Chelmsford has its own zip code (01863), library, post office, fire station, water district, and local calling area, it is run by the same local town government and shares a school district with Chelmsford.
North Chelmsford is smaller and more densely populated than neighboring Chelmsford. North Chelmsford's separate identity, though not a seriously debated issue, is still a topic of discussion - the Lowell Sun ran an article on August 7, 2005 describing the situation as "Chelmsford's Civil War Still Raging On." Bumper stickers such as "I'm from North Chelmsford - Don't Tread On Me" can be seen around town.
