Carl Christian Brenner (August 1 (or 10), 1838 – July 22, 1888) was a German-born American artist.
In 1863, Brenner was commissioned by Louisville Masons to paint panoramic Civil War battle scenes inside their lodge.
He was one of a group of Louisville artists known as "Tonalists", whose muted colors evoked mood.
Brenner's works were exhibited at the Louisville Industrial Exposition in 1873 and at the Pennsylvania Academy of Fine Arts in 1876.
One of his most notable paintings is Falls of the Cumberland River, Whitley County, Kentucky, executed 1881–82.
