Webb County is a county located in the U.S. state of Texas. As of the 2020 census, its population was 267,114. Its county seat is Laredo. The county was named after James Webb (1792–1856), who served as secretary of the treasury, secretary of state, and attorney general of the Republic of Texas, and later judge of the United States District Court following the admission of Texas to statehood. By area, Webb County is the largest county in South Texas and the sixth-largest in the state. Webb County comprises the Laredo metropolitan area. Webb County is the only county in the United States to border three foreign states or provinces, sharing borders with Coahuila, Nuevo Leon, and Tamaulipas.

Webb County has a minority majority, with 95.2% of the population of the county identifying as Hispanic. This makes Webb the county with the second-highest proportion of Hispanic people in the continental United States after Starr County, and it has the highest proportion of Hispanic people among counties with a population over 100,000.

Webb County was split in 1856. Encinal County was established on February 1, 1856, and was to have consisted of the eastern portion of Webb County. However, Encinal County was never organized and was finally dissolved on March 12, 1899, with its territory returned as part of Webb County.

Much of Webb County history is based on the prevalence of ranching in the 19th century and continuing thereafter. The Webb County Heritage Foundation is a nonprofit organization that seeks to preserve documents and artifacts of the past to guarantee that the regional history is not lost to upcoming generations. In 2015, the foundation, headed by President James E. Moore, presented Heritage Awards to such local notables as the artist Janet Krueger, journalist Maria Eugenia Guerra, and Laredo Community College art instructor Martha F. Fenstermaker (1943-2014).

According to the U.S. Census Bureau, the county has a total area of 3,376 square miles (8,740 km), of which 3,361 square miles (8,700 km) are land and 14 square miles (36 km) (0.4%) are covered by water.

The Webb County - City of Laredo Regional Mobility Authority has responsibility for a comprehensive transport system in the region.

Given the overwhelming Democratic allegiance in Webb County, Republicans rarely offer candidates for county office. In the March 4, 2014, primary, 1,151 (4.6 percent) voted in the Republican primary in Webb County, compared to 23,958 (95.4 percent) in the Democratic contests. Webb County elections administrator Carlos Villarreal reported a 24% turnout in the November 4, 2014, general election in Webb County. County officials have requested that Villarreal develop a plan to increase turnout for 2016. County Democratic Chairman Alberto Torres, Jr., suggested improvements in the election division website with clear maps of voter boundaries. Torres said that such better services might motivate persons to vote regularly. Despite its long-term Democratic streak, since 2016 Webb County has been trending more towards the Republican party, due to Donald Trump attracting more Hispanic voters. This mirrors the same trend seen in other counties in South Texas. In 2024, the county flipped Republican by a slim majority, the first time it had done so since 1912.

Three school districts serve Webb County:

• Laredo Independent School District
• United Independent School District
• Webb Consolidated Independent School District

Prior to 1994, Webb CISD served only Bruni and Oilton. Mirando City Independent School District served the community of Mirando City from 1923 to 2005. Prior to 1994, all Mirando City children attended Mirando City ISD schools. After the spring of 1994, Mirando City High School closed. Therefore, from the fall of 1994 to July 1, 2005, WCISD served high schoolers from Mirando City, while Mirando Elementary School in the Mirando City ISD served pupils from kindergarten through eighth grade. On May 9, 2005, the Texas Education Agency ordered the closure of Mirando City ISD. The district closed on July 1, 2005, and all students were rezoned to Webb CISD schools.

The private Holding Institute is a former United Methodist boarding school operating as a downtown Laredo community center.

All residents are zoned to Laredo College.
