Denton is a city in and the county seat of Denton County, Texas, United States. With a population of 139,869 as of 2020, it is the 27th-most populous city in Texas, the 197th-most populous city in the United States, and the 12th-most populous city in the Dallas–Fort Worth metroplex.

A Texas land grant led to the formation of Denton County in 1846, and the city was incorporated in 1866. Both were named after pioneer and Texas militia captain John B. Denton. The arrival of a railroad line in the city in 1881 spurred population, and the establishment of the University of North Texas in 1890 and Texas Woman’s University in 1901 distinguished the city from neighboring regions. After the construction of Dallas/Fort Worth International Airport finished in 1974, the city had more rapid growth; as of 2011, Denton was the seventh-fastest growing city with a population over 100,000 in the country.

Located on the far north end of the Dallas–Fort Worth metroplex in North Texas on Interstate 35, Denton is known for its active music life; the North Texas State Fair and Rodeo, Denton Arts and Jazz Festival, and 35 Denton Music Festival attract over 300,000 people to the city each year.
