The Main Street Historic District encompasses the historic commercial heart of Rockland, Maine. Located on several blocks of Main Street (United States Route 1), the district has a well-preserved collection of commercial architecture dating from the mid-19th to early 20th centuries, the period of the city's height as a shipbuilding and industrial lime processing center. The district was listed on the National Register of Historic Places in 1978, and enlarged in 2012.
