Oliver Perry Temple (January 27, 1820 – November 2, 1907) was an American attorney, author, judge, and economic promoter active primarily in East Tennessee in the latter half of the 19th century. During the months leading up to the Civil War, Temple played a pivotal role in organizing East Tennessee's Unionists. In June 1861, he drafted the final resolutions of the pro-Union East Tennessee Convention, and spent much of the first half of the war providing legal defense for Unionists who had been charged with treason by Confederate authorities.
