Overview

Houston is the largest city in Texas and the fourth-largest city in the United States. It lies in south-east Texas near Galveston Bay and the Gulf of Mexico, at the meeting of Buffalo Bayou and White Oak Bayou. The city was founded in 1836 and named after Sam Houston, the general who won Texas its independence. It grew as a port and a railway hub, then boomed with the discovery of oil at Spindletop in 1901.

About 2.4 million people lived in Houston in 2025, and about 7.9 million in its metropolitan area. The city is one of the most diverse in the United States, and its economy runs on energy: Houston is the centre of the American oil and gas industry, and its port is one of the busiest in the country. It is also home to the Texas Medical Center, the largest medical complex in the world, and to NASA's Johnson Space Center.

Houston is known as Space City, because Mission Control for human spaceflight is here. Its museum district, its food — from barbecue to Vietnamese and Mexican cooking — and its parks along Buffalo Bayou draw visitors from across Texas. The city has no formal zoning, which gives it an unusual, sprawling shape.
