The Alfred Webb Investment Properties in southeast Portland in the U.S. state of Oregon consists of four Queen Anne cottages listed on the National Register of Historic Places. Built in 1891, they were added to the register in 1989. Webb, who owned Webb Safe and Lock Company, developed several residential properties in southeast Portland. He and his wife, Martha, who owned the four Queen Anne cottages from 1891 to 1928, lived elsewhere in the neighborhood and rented out the cottages. Subsequent owners through at least 1989 continued to maintain the dwellings as rental properties.
