Thomas Jefferson Bowers[1] (1828 – August 26, 1893) was an American lawyer and jurist who was Chief Justice of the Idaho Territorial Supreme Court from 1868 to 1869.

[2] He was nominated for Chief Justice of the Idaho Territorial Supreme Court by President Andrew Johnson on July 15, 1868, and he was confirmed by the senate three days later.

[4] A Democrat, Bowers was replaced as chief justice in 1869 by David Noggle when Ulysses S. Grant, a Republican, became president.

[2] Noggle, confirmed on April 9, arrived in Idaho and relieved Bowers of his judgeship on June 3, 1869, over the latter's protests.

[5][6] After his time on the territorial court, Bowers incorporated the Ida Elmore Mining Company in 1869 and served briefly as corporate secretary and trustee,[7] but he soon left Idaho.
