The Reed Smoot House, also known as Mrs. Harlow E. Smoot House, was the home of Reed Smoot from 1892 to his death in 1941, and is located at 183 E. 100 South, Provo, Utah, United States. Smoot was a prominent US Senator best known for advocacy of protectionism and the Smoot–Hawley Tariff Act.

It was declared a National Historic Landmark in 1976.

Smoot himself drew the first designs for the house, and Richard K.A. Kletting completed the design. The house cost over four thousand dollars to complete. "Victorian Eclectic in design, it is a Stately, solid, early Mormon square block home with some Victorian exuberance displayed in the detailing. The home is linked with Utah's early political and religious history, and is the site of several visits from U.S. presidents in the early twentieth century (Historic Provo p. 20)." This house was nominated to be named to the Provo City Landmark Register on April 28, 1995. It is currently a private residence.
