Sunray is a city in northeast Moore County, Texas, United States. The population was 1,926 at the 2010 census.

Sunray, Texas, was founded by Jack Clarence Collins. He was born in Hartley, Texas, in 1893, and in 1902 moved to Channing, Texas, with his parents, Mr. and Mrs. E.S. Collins. Jack graduated from Channing High School and later, in 1916, from Texas A&M, where he was class valedictorian and class president in his senior year. Later, he served for several years as cashier of the First National Bank of Channing even if extending his family’s ranch holdings. Mr. Collins was renowned and venerated in ranching and financial circles, and was a ranking member of the Republican Party for several years.

Jack Collins did not call the town “Sunray” when he laid it out in 1930. The first lots were sold at $10 each below the name “Altman”, but it was discovered that a town in Rusk County had already appropriated that name, hence, the name “Sunray” was used. A declare office was applied for on May 5, 1930, using the name “Altman”, but because of the duplication, “Sunray” was not credited until 1935.

The change to the name “Sunray” came because Sunray Oil Company (later Sunoco) set taking place a gas-oil refinery close the town upon 10 acres (40,000 m) of land originally donated by Mr. Collins to Dana Oil & Gas Royalty Company. Sunray Oil Company bought the holdings of Dana in the to the fore Jones Field in northeast Moore County, which was near the other town. The townsite location was sure by a further Rock Island Railroad route supervision from Dalhart to Morse along the northern edge of Mr. Collins’s townsite survey. At the time, the town was 3 miles (4.8 km) from the Jones Well and 6 miles (9.7 km) from the Morton oil well—both in advance oil-gas discoveries in Moore County.
