Haroldson Lafayette Hunt Jr. was an American oil tycoon. By trading poker winnings for oil rights according to legend, but more likely through money he gained from successful speculation in oil leases, he ultimately secured title to much of the East Texas Oil Field, one of the world's largest oil deposits. He acquired rights to East Texas oil lands initially through a $30,000 land purchase from oil speculator Dad Joiner, and founded Hunt Oil in 1936. From it and his other acquisitions, which included diverse interests in publishing, cosmetics, pecan farming, and health food producers, he accrued a fortune that was among the world's largest. In the 1950s, his Facts Forum Foundation supported highly conservative newspaper columns and radio programs, some of which he authored and produced himself, and for which he became known. At his death, he was reputed to have one of the highest net worths of any individual in the world, a fortune estimated between $2–3 billion dollars.

The East Texas Oil Field is a large oil and gas field in east Texas. Covering 140,000 acres (57,000 ha) and parts of five counties, and having 30,340 historic and active oil wells, it is the second-largest oil field in the United States outside Alaska, and first in total volume of oil recovered since its discovery in 1930. Over 5.42 billion barrels (862,000,000 m3) of oil have been produced from it to-date. It is a component of the Mid-continent oil province, the huge region of petroleum deposits extending from Kansas to New Mexico to the Gulf of Mexico.
