Carl Caspar Giers (April 28, 1828 – May 24, 1877) was a German-born American photographer active primarily in Nashville, Tennessee, in the mid-19th century. In documenting Nashville's rapid postwar growth and expansion, he photographed numerous prominent individuals, including political leaders, Civil War generals, and important business and cultural figures. A popular resident of the city, he served one term in the Tennessee House of Representatives (1874–1875), having been the nominee of both the Democratic and Republican parties.
