Merrimack Mill Village Historic District, Industrial heritage district in Huntsville, United States.

Merrimack Mill Village Historic District is an industrial neighborhood in Huntsville with residential buildings constructed between 1900 and 1937 for factory workers. The area contains roughly 269 remaining houses displaying different architectural styles from that industrial period.

The Merrimack Manufacturing Company established this industrial complex in 1900, building a cotton mill that grew into a major employer. The factory and the surrounding worker houses developed together as the company expanded to attract and house its workforce.

The village grid is broken by a Y-shaped street that led to the mill, with the superintendent's house set inside the Y; the layout copies Merrimack's Massachusetts village platted in 1820. House types carry names like Type A shotgun duplex, Type J I-house and Type L cross-gable duplex; the 96 Type L houses form the largest collection of the type in the South.

Visitors can walk through the neighborhood and discover the different house types and street layouts on their own. It helps to move slowly and take time to observe the architecture and how the houses are arranged throughout the area.

The 96 Type L houses, mostly built before 1910, form the largest collection of this two-story cross-gable duplex in the South. The village grid, broken by a Y-shaped street leading to the mill site, copies the layout of Merrimack's Massachusetts village platted in 1820. The mills were demolished in 1992 and their land is now soccer fields.
