Preston Hopkins Leslie (March 8, 1819 – February 7, 1907) was the 26th Governor of Kentucky from 1871 to 1875 and territorial governor of Montana from 1887 to 1889. He ascended to the office of governor by three different means. First, he succeeded Kentucky governor John W. Stevenson upon the latter's resignation to accept a seat in the United States Senate in 1871. Later that year, he was elected to a full term as governor, defeating John Marshall Harlan in the general election.
