The James P. Newton House and Maid Cottage are historic buildings located in Sioux City, Iowa, United States.

Newton was a prominent local businessman associated with Haskins Bros. & Co., whose principal product was soap.

[2] The 1½-story frame American Craftsman house and the single-story frame maid's house near the alley feature clapboard siding, porches with square columns, and low pitched hipped roofs with dormers.

The bands of color and the wide eaves are elements from the Prairie School style for which Steele would become well known.
