Katy is a city located in Harris, Fort Bend and Waller Counties in the U.S. state of Texas, within the Houston–Sugar Land–Baytown metropolitan area. The population was 11,775 at the 2000 census.
Katy, suburb of Houston, Texas, is named for the Missouri-Kansas-Texas Railroad (commonly referred to as the "K-T Railroad", now a part of Union Pacific) that ran through Katy in the 19th century. Katy was once known as Cane Island. The name is derived from Cane Island Creek which runs just west of downtown. Cane Creek is a branch of Buffalo Bayou. The origins of the name Cane Island are believed to be from the fact that Katy was once a major sugar cane producer and rice producer. To commemorate the importance of rice to the Katy community, the Chamber of Commerce holds the Rice Harvest Festival every second weekend of October. The railroad had been built through the community by the end of 1893.
Katy incorporated in 1945. Because of the incorporation, Houston did not incorporate Katy's territory into its city limits.
