Lake County is a county in the U.S. state of Ohio. As of the 2020 census, about 232,603 people lived there. Its main town, called the county seat, is Painesville. The biggest city in Lake County is Mentor.
The county was created on March 6, 1840. It was formed from parts of Cuyahoga and Geauga counties. Lake County got its name because it's located right on the southern shore of Lake Erie. A large part of the county's total area is actually under Lake Erie. Lake County is also part of the larger Cleveland Metropolitan Area.

History
Long ago, the land that is now Lake County was home to the Erie people. This was before the French arrived in the early 1600s. The French considered this area part of their colony, New France.
In 1763, the land was given to Great Britain. It became part of the Province of Quebec in 1774. After the American Revolutionary War, it became part of the Connecticut Western Reserve in the Northwest Territory. The Connecticut Land Company bought it in 1795. Finally, in March 1840, Lake County was officially separated from Geauga County.
Geography
Lake County covers a total area of 979 square miles (2,540 km2). Out of this, 227 square miles (590 km2) is land, and 752 square miles (1,950 km2) (which is 77%) is water. This makes it Ohio's smallest county by land area. However, it's the third-largest by total area because of the land it owns under Lake Erie.
The county has a 31-mile long coastline along Lake Erie. Lake County also shares an international border with Ontario, Canada, across Lake Erie.
