Thomas Holdup Stevens Jr. (27 May 1819 – 15 May 1896) was an admiral of the United States Navy who fought in the American Civil War.

Following a tour at the Washington Navy Yard and coast survey duty at New York, he attended the Naval School at Philadelphia, stood his examination on 2 June 1842, and was warranted a passed midshipman on 2 July.

From then until the outbreak of the Civil War, Stevens served with the Home Squadron, principally in Roanoke, Colorado, and Michigan.

[1] Between New Year's Day and 4 March 1862, he blockaded the coast of Florida and helped to capture Fort Clinch, and the towns of Fernandina and St. Mary's.

On 18 June 1863, Commander Stevens was detached from Sonoma at New York and, on 3 August, he was directed to report to the South Atlantic Blockading Squadron.

Admiral David Farragut then ordered him to command the double-turreted monitor Winnebago which he led in attacks on Fort Powell and in the Battle of Mobile Bay on the 5th.

[2] His son Thomas Holdup Stevens III (12 July 1848 – 3 October 1914) was an 1868 United States Naval Academy graduate who retired from the Navy as a rear admiral in February 1905.
