Charles Cecil Dennis (1931 – April 22, 1980) was a Liberian political figure who served as Minister of Foreign Affairs under President William Tolbert from 1973 until the coup d'état by Samuel Doe on April 12, 1980. Along with other members of Tolbert's Cabinet, he was promptly put on trial and executed by firing squad ten days after the coup.
He was preceded as Foreign Minister by Rocheforte Lafayette Weeks and eventually replaced by Gabriel Bacchus Matthews.
