Pasco County was created in 1887 from the southern part of Hernando County. It was named for Samuel Pasco, who served in the Confederate Army, the state legislature and in the United States Senate from 1887 to 1899. The earliest towns were Anclote, Blanton, Dade City, Earnestville, Fort Dade, Macon (Trilby), Lacoochee and San Antonio. Citrus was an important industry when the county was formed, although a decline followed a freeze in 1895. Several large sawmills operated in the county in the early part of the twentieth century. During the Florida land boom of the 1920s, New Port Richey became the winter home of silent screen star Thomas Meighan and golfer Gene Sarazen; Meighan attempted to bring other Hollywood figures to the city. The county has experienced significant population growth since the 1960s. The growth began along the Gulf coast but is now occurring most rapidly in areas north of Tampa.

Located on the Gulf of Mexico in the Tampa Bay area, Pasco is part of a nine-county region referred to as the “Nature Coast.” Pasco County has a total of 742 square miles with more than 100 square miles of managed recreational facilities, including parks, four artificial reefs (one made up of surplus military tanks), more than 25 golf courses, and three State-designated canoe trails. The possibilities to enjoy the outdoors and nature are unlimited.
