John Henry “Harry” Phelan (December 11, 1877 – May 19, 1957), was an American oil producer and philanthropist. In partnership with Miles Franklin Yount, he worked for the Yount-Lee Oil Company. After the oil company’s success at Spindletop, Yount-Lee was bought in 1935 by Stanolind Oil, when Phelan was treasurer of the firm, a deal the Handbook of Texas calls "the third largest cash transaction in American business history". Before going into oil, he formed the Phelan-Josey Wholesale Company, a regional grocery distributor in Southeast Texas, upon his arrival in Beaumont, Texas in 1902.
