Charles Dickens Clark (October 7, 1847 – March 15, 1908) was a United States federal judge.
Born in Laurel Cove, Tennessee, Clark received a B.A. from Burritt College in 1871 and an LL.B. from Cumberland University in 1873. He was on the staff of Confederate States General George G. Dibrell in Richmond, Virginia from 1864 to 1865. He was in private practice in Manchester, Tennessee from 1876 to 1883, and in Chattanooga, Tennessee from 1883 to 1895.
On December 17, 1894, Clark was nominated by President Grover Cleveland to seats on the United States District Court for the Middle District of Tennessee and the United States District Court for the Eastern District of Tennessee, both vacated by David M. Key. Clark was confirmed by the United States Senate on January 21, 1895, and received his commission the same day. He served on the court until his death, in Chattanooga.
