Thomas Brown Holmes Stenhouse (21 February 1825 – 7 March 1882) was an early Mormon pioneer and missionary who later became a Godbeite and with his wife, Fanny Stenhouse, became a vocal opponent of the Church of Jesus Christ of Latter-day Saints (LDS Church).
In 1850, Stenhouse married Fanny Warn and shortly thereafter joined Lorenzo Snow and Joseph Toronto on a mission to Italy; they became the first LDS Church missionaries to preach in that country.
Their daughter, Clara Federata Stenhouse, married Joseph Angell Young.
In 1870, Stenhouse was convinced by the writings of William S. Godbe, who criticised LDS Church President Brigham Young on political and religious grounds.
Stenhouse's most famous work is his 1873 The Rocky Mountain Saints: A Full and Complete History of the Mormons.
