League City is a city in the U.S. state of Texas, in Galveston County, within the Greater Houston metropolitan area. The population 114,392 at the 2020 census.

The city of League City has a small portion north of Clear Creek within Harris County zoned for residential and commercial uses. It is home to several waterside resorts, such as South Shore Harbor Resort and Conference Center and Waterford Harbor and Yacht Club Marina, popular with residents of nearby Houston. Between 2000 and 2005, League City surpassed Galveston as Galveston County's largest city.

League City was settled at the former site of a Karankawa Indian village. Three families, the Butlers, the Cowarts, and the Perkinses, are considered to be founding families of the city. The Winfield Family has also recently been acknowledged as a founding family by the City Government. The Cowart family settled on a creek now called Cowart's Creek after them (now often called "Coward's Creek"). The Perkins family built on a creek notably lined with magnolia trees and named it Magnolia Bayou. The Butler family settled inland. The Winfield Family purchased land in League City from the great nephew of Stephen F. Austin and moved there, to a place near what is now Hobbs Road.

The first resident of the town proper, George W. Butler, arrived from Louisiana in 1854 and settled at the junction of Clear Creek and Chigger Bayou. The area was known as Butler's Ranch or Clear Creek until J. C. League acquired the land from a man named Muldoon on his entering the priesthood. League laid out his townsite along the Galveston, Houston, and Henderson Railroad, already established in the area. This began a small feud over the name, as Butler was the postmaster. The name was changed several times, alternating between Clear Creek and the new League City. In the end, League City was chosen.

In 1907, League had two railroad flatcars of live oak trees left by the railroad tracks. These were for the residents to plant on their property. Butler and his son Milby supervised the planting of these trees, now known as the Butler Oaks. Many of them line Main Street to this day.

Starting in the early 1970s, the bodies of 30 murdered women were discovered in Galveston County, with 4 being discovered in League City, and more have gone missing from the same area. This location has become known as the Texas Killing Fields.

In the 2000s, rising real estate costs in Galveston forced many families to move to other areas, including League City. This meant an influx of children out of Galveston ISD and into other school districts like Clear Creek ISD and Dickinson ISD.

League City became an incorporated city in 1962. League City's government consists of seven council members and the mayor. The mayor is a full voting member of the council. The city's charter is purported to be a strong mayor form of government, but this issue has been debated for years. By ordinance, a city administrator position was created under Mayor Leonard Cruse. The ordinance was amended in May 2010 to create a council-manager government. According to the ordinance, "...shall consist of a mayor and council members, elected by the people and responsible to the people, and a city manager, appointed by and responsible to the council for proper administration of the affairs of the city."

In 2011 an officer accused the police chief, Michael Jez, of giving officers ticket quotas, which are illegal in the state of Texas. In November city council voted to place Chief Jez on administrative leave. The council did not give a reason and Jez cited philosophical differences for the separation. Much speculation was made that the decision was a reaction to the allegation made, but neither side ever admitted to any wrongdoing.

In 2014, the police department moved to a new joint Public Safety Building that is shared with Police and Fire administration as well as housing the police department, dispatch, and the city jail. The building is across the street from the old police department that now houses other city offices that were previously in leased space. The city held an open house in January 2015 to serve as a grand opening to the public, allowing citizens to come see the inner workings of the police department.
