Gotland County (Gotlands län) is a county or län of Sweden. Gotland is located in the Baltic Sea to the east of Öland, and is the largest of Sweden's islands. Counties are usually sub-divided into municipalities, but Gotland County only consists of one municipality: Gotland Municipality. Gotland County is the only county in Sweden that is not governed by a county council. The municipality handles the tasks that are otherwise handled by the county council, mainly health care and public transport. Like other counties, Gotland has a County Administrative Board that oversees implementation of the Swedish state government. Both the County Administrative Board and the municipality have their seat in the largest city Visby, with over 22,000 inhabitants.

The counties of Sweden are no longer officially administrative units, but are used when reporting population size, politics, etc. In this case the province, the county and the municipality all have identical borders and cover an area of 3151 km² (3151 km² when excluding the lakes and rivers).

Gotland is the only Swedish county that is not administered by a county council. Instead, the municipality is tasked with the responsibilities of a county, including public health care and public transport.

The main aim of the County Administrative Board is to fulfil the goals set in national politics by the Riksdag and the Government, to coordinate the interests and promote the development of the county, to establish regional goals and safeguard the due process of law in the handling of each case. The County Administrative Board is a Government agency headed by a Governor. See List of Gotland Governors.
