Gleasondale, formerly known as Rockbottom or Rock Bottom, is a village in the towns of Hudson and Stow in Middlesex County, Massachusetts, United States. It could be considered to start where Main Street in Hudson becomes Wilkins Street, and runs until the intersection of Gleasondale Road and Great Road in Stow. According to the Geographic Names Information System (GNIS), Gleasondale is a "populated place" and is named after Benjamin W. Gleason and Samuel J. Dale. It has an elevation of 187 feet, or 57 meters. Until its closure in 1965, the Gleasondale Station — one of two train stations in Hudson — served the village. It was originally operated by the Central Massachusetts Railroad Company, and later by Boston & Maine. The station's name is printed as "Rocky-bottom" in the 1888 map of the Central Massachusetts Railroad's route at right.
Today, Gleasondale has a few residential buildings, plus a small industrial complex. It does not a have a large enough population to boast its own post office, instead using the same zip code as Stow: 01775.
