Deer Park is a city in the U.S. state of Texas within the Houston–Sugar Land–Baytown metropolitan area. The city is located in Harris County and is situated in Southeast Texas.
Deer Park was founded in 1892 by Simeon H. West, a farmer, retired legislator, and much-travelled adventurer from Illinois. He named the town for the large number of deer that roamed the Gulf plains. A railroad station opened later that year and a post office followed in 1893. The subdivision was established in 1893 and was the site of a Galveston, Harrisburg and San Antonio Railway station by about 1894. A Deer Park post office was established in 1893, discontinued in 1919, and re-established in 1930.
