The Dooly Building was an office building designed by architect Louis Sullivan in Salt Lake City, Utah, at 109 West Second South Street. It was one of four buildings Sullivan designed in the western United States. Built in 1892, it was demolished in 1964. It was described by the Historic American Buildings Survey as the best work by Sullivan in the west. The building's contractor was Bernard Henry Lichter. Tenants included a post office, the Alta Club, and offices of architects and engineers. The Dooly Building was named for John E. Dooly, a member of the building's investment syndicate and a prominent civic leader.
