The Maria Baldwin House is a National Historic Landmark located at 196 Prospect Street, Cambridge, Massachusetts, United States.

[2][3] The main block of the Baldwin House is a 2+1⁄2-story wood-frame structure resting on a brick foundation, with a side-gable roof.

It is a duplex, a total of six bays in width, with a pair of doorways sheltered by portico supported by three Ionic columns.

There is a simple entablature below the main roofline, running around the house; the gable ends on the sides are fully enclosed.

At that time she was the first black woman in New England to hold such a high educational position, and was one of only two female masters in the Cambridge schools.
