Ashlawn, also called the Joshua Perkins House, is a two-story, central-hall frame farmhouse dating from the 18th century in Hanover, Connecticut.

Ashlawn's main house has a five-bay front facade with pilasters supporting broken-base pediments. The inside has well-documented woodwork for its moldings and wainscotting. The house has integrated an older structure, likely a central-chimney structure built in the second quarter of the 18th century, as an ell. In 2002, the house was maintained by Ruth Rosiene, a descendant of the Perkinses. Ashlawn is listed on the National Register of Historic Places as an example of Georgian architecture and locally important for its connection with the Perkins family.
