The Knight–Mangum House is a historic house located in Provo, Utah, United States. It is listed on the National Register of Historic Places. The mansion was built in the old English Tudor style, completed in 1908. It was built for Mr. W. Lester Mangum and his wife Jennie Knight Mangum. Mrs. Mangum was the daughter of the famous Utah mining man, Jesse Knight. The lot was purchased for $3,500 and the home was built at a cost of about $40,000. The Mangum family was able to afford the home due to the fact that they had sold their shares in Jesse Knight's mine located in , Utah, for eight dollars a share. They had purchased the shares for only twenty cents a share, so the excess allowed them enough funds to purchase the home. The contractors for the home were the Alexandis Brothers of Provo.
