The Andover Street Historic District is a linear residential historic district in the Belvidere neighborhood of eastern Lowell, Massachusetts. The district encompasses large, fashionable houses and estates that were built between the 1860s and the 1930s. It includes properties at 245—834 Andover Street, and at 569 and 579 East Merrimack Street. In the first phase of growth, between the 1860s and 1890s, Italianate and Queen AnneVictorian houses were built. These were followed from the 1890s the 1930s by a series of high quality Colonial Revival homes. Most of the later properties are of smaller size than the earlier buildings, although the quality of workmanship remained high. The oldest properties in the district are the Federal-style Harry F. Worcester House (658 Andover Street, built 1802) and The Manse at 282 Andover Street, a stone Gothic Revival structure built c. 1847. The Elijah Read House at 578 Andover Street is said to be the finest Italianate house in the area.
