The North Lexington Street Historic District is a residential historic district at 508–536 North Lexington Street in Waltham, Massachusetts.

It consists of a cluster of four houses and their associated outbuildings, built around the turn of the 20th century, and unusual for its state of cohesion and preservation given the busy nature of Lexington Street.

The house at 508 Lexington was built in 1865 and extensively restyled in 1905; it retains some Italianate styling.

[2] The district was listed on the National Register of Historic Places in 1989.
