The Nahum Hardy House is a historic house at 724 Lexington Street in Waltham, Massachusetts. The -story wood frame house was built c. 1845, and is a well-preserved local example of a Greek Revival side-hall house. It has a fully pedimented gable end, a full entablature with dentil-like peg moulding, and a single-story porch with Tuscan columns. The corner boards are pilastered. The house stands on land purchased by Nahum Hardy from Harvard College in 1839.
The house was listed on the National Register of Historic Places in 1989.
