Frisco is a city in the U.S. state of Texas, located in Collin and Denton counties. It is part of the Dallas–Fort Worth metroplex (DFW) and about from both Dallas Love Field and Dallas/Fort Worth International Airport. Its population was 200,509 in the 2020 U.S. census.
Frisco was the fastest-growing city in the United States in 2017, and also from 2000 to 2009. In the late 1990s, the northern DFW suburban development tide hit the northern border of Plano and spilled into Frisco, sparking rapid growth into the 2000s. Like many of the cities in Dallas's northern exurbs, Frisco serves as a bedroom community for professionals who work in DFW. Since 2003, Frisco has received the designation Tree City USA from the National Arbor Day Foundation.
The United States Census Bureau defines an urban area of northern Dallas-area suburbs that are separated from the Dallas–Fort Worth urban area, with McKinney and Frisco as the principal cities: the McKinney–Frisco, Texas, urban area had a population of 504,803 as of the 2020 census, ranked 83rd in the United States.
In 1902, a line of the St. Louis–San Francisco Railway ("the Frisco") was being built through the area, and periodic watering stops were needed along the route for the steam locomotives. The current settlement of Lebanon was on Preston Ridge and was too high in elevation, so the watering stop was placed about 4 miles (6 km) to the west, on lower ground. A community grew around this train stop, and some Lebanon residents moved their houses to the new community on logs. The new town was originally named Emerson, but the U.S. Postal Service rejected the name as too similar to another community, Emberson, in Lamar County.
In 1904, the town's residents chose "Frisco City" in honor of the St. Louis–San Francisco Railway. This name was later shortened to Frisco.
The city is also in Tornado Alley, with the most recent confirmed tornado in 2024, as an EF-0 tornado, near the UNT Frisco Campus.
