Charles Francis Risk (August 19, 1897 – December 26, 1943) was an American lawyer and World War I veteran who served two non-consecutive terms as a U.S. Representative from Rhode Island in the 1930s and 1940s.

Born in Central Falls, Rhode Island, Risk attended the public and high schools there.

He graduated from the law department of Georgetown University in 1922, and was admitted to the bar in 1923, taking up a practice in his home town the same year.

Risk was elected to the Seventy-fourth Congress as a Republican, filling the vacancy caused by the resignation of Francis B. Condon; he served from August 6, 1935, to January 3, 1937.

He died in Saylesville, in the township of Lincoln, Rhode Island, December 26, 1943, and was buried in St. Francis Cemetery in Pawtucket.
