Russell McWhortor Cunningham (August 25 1855–June 6 1921) was an American Democratic politician who was the acting Governor of Alabama from April 25 1904 to March 5 1905. He was lieutenant governor when Governor William D. Jelks fell ill and left the state for treatment, and since the Alabama Constitution requires that if the governor leave the state for more than 20 days, the lieutenant governor must act as governor until their return.
