The House at 90 Prospect Street in Wakefield, Massachusetts, is one of three houses in the family compound of Elizabeth Boit. Built in 1913, the compound of which this house is a part is the only estate of one of Wakefield's major industrial figures to survive. The house was listed on the National Register of Historic Places in 1989.

Elizabeth Boit, co-founder of the Harvard Knitting Mills, was one of the first highly placed female executive in the male-dominated management ranks of textile firms at the turn of the 20th century, and is believed to be the only woman in a top executive position in the United States textile industry in 1923. She pioneered improvements in worker conditions, offering factory workers health care, and providing bonuses based on company profits. The compound she built at Chestnut and Prospect Streets, on the summit of Cowdry's Hill, is the only surviving estate of Wakefield's leading business executives.

Boit's three houses were designed by local architect Harland Perkins. They were situated in an estate compound on the summit of Cowdry's Hill, that included three residences, formal gardens, a playhouse, and a greenhouse. All three residences, 90 and 88 Prospect Street, and 127 Chestnut Street (1910-1913), were designed in the English Cottage style. The stucco structures have red tile roofs, recessed entries, exposed purlins, and irregular fenestration. This house is 1+1⁄2 stories in height, with its entry set under a cross-gable roof section with a clipped gable. There are recessed porches on either side, supported by heavy columns.
