Thomas Ogden Osborn (August 11, 1832 – March 27, 1904) was an American lawyer, soldier, and diplomat who served as a general in the Union Army during the American Civil War. He was also the U.S. Minister to Argentina from 1874 to 1885.
Thomas Osborn was born near the rural village of Jersey in Licking County, Ohio. In 1854 he graduated from Ohio University at Athens. Osborn studied law in Crawfordsville, Indiana under future Civil War general Lew Wallace and moved to Chicago, where he established a law practice in 1858.
After the start of the war, Osborn became the lieutenant colonel of the 39th Illinois Infantry on October 11, 1861, and was promoted to colonel the following year on January 1. He led the regiment in several campaigns and battles in the Eastern Theater.
Osborn and his command saw action in the 1862 Valley Campaign against Confederate forces under Lt. Gen. Thomas Jonathan "Stonewall" Jackson, participating in the Battle of Port Republic on June 9. From July until September 1863, Osborn took part in Union operations against Charleston, South Carolina, including attacks on Fort Wagner and Fort Sumter.
