Lake County is a county in the central portion of the U.S. state of Florida. As of the 2020 census, the population was 383,956. Its county seat is Tavares, and its largest city is Clermont. Lake County is included in the Orlando–Kissimmee–Sanford Metropolitan Statistical Area.

Lake County was created in 1887 from portions of Sumter and Orange counties. It was named for the many lakes contained within its borders (250 named lakes and 1,735 other bodies of water).

In the 1800s, the two main industries in the area were growing cotton and breeding cattle. In the latter part of the 19th century, people started to grow citrus trees. Citrus was introduced by Melton Haynes. Throughout the 1940s and 50s, citrus production increased and grew into the area's leading industry. The December 1989 United States cold wave destroyed most of the citrus groves, dealing an economic blow from which many growers could not recover. Grove owners sold massive amounts of land to developers, resulting in increasing urban sprawl.

According to the U.S. Census Bureau, the county has a total area of 1,157 square miles (3,000 km), of which 938 square miles (2,430 km) is land and 219 square miles (570 km) (18.9%) is water.

Sugarloaf Mountain is the highest point in peninsular Florida, at 312 feet (95 m) above sea level.

The Lake County Library System was established in 1982 by Lake County Ordinance 1982-18 following the establishment of the Lake County Library Planning Advisory Board in 1975. Today it is governed by the Lake County Board of County Commissioners. The library system is made up of 6 branch libraries and 10 municipal libraries:

• Astor County Library, Astor
• Cagan Crossings Community Library, built in 2008 in Clermont
• Cooper Memorial Library: The Cooper Memorial Library's history began in 1905 when a traveling salesman stopped by a boarding house run by the Benjamin McCain family and promised to donate enough books to start a town library if he was able to sell his Chautauqua lectures. Money was contributed, but very few lectures occurred, and books were never donated. Money that was to be used for the final payment for the lecture series was instead used to start a library. The first librarian of the library was Ms. Payson Pierce, who offered her own home for book storage as well as opened her home to the public. In 1914, a permanent structure was built. Women of the Library Club supported the library until 1936 when the Clermont City Council agreed to maintain it. In 2002, Cooper Memorial became a branch of the Lake County Library System.
• East Lake County Library, Sorrento
• Eustis Memorial Library, Eustis
• Fruitland Park Library first began in 1916 from the donation of books from the Bosanquet and Dwight families. Twenty years later, under the joint support of the women of St. Paul's Catholic Church, Holy Trinity Episcopal Church, and the Community Methodist Church, it became a community library. In 1970, Fruitland Park Library employed its first salaried librarian.
• Helen Lehmann Memorial Library, Montverde
• Lady Lake Public Library, Lady Lake
• Leesburg Public Library, Leesburg
• Marianne Beck Memorial Library: The Marianne Beck Memorial Library began in 1989 as an Eagle Scout project in a former carport in Howey-in-the-Hills, Florida. The local community raised $50,000 to remodel a former convenience store that was purchased by the town for the new library.
