Visby Airport (IATA: VBY, ICAO: ESSV) is the primary commercial airport serving Visby, the capital of Gotland, Sweden's largest island in the Baltic Sea. It provides essential air links between the island and mainland Sweden, particularly to Stockholm, making it a vital transport node for both residents and tourists. The airport sees significant seasonal traffic fluctuations, with passenger numbers rising sharply during summer months when tourists flock to Gotland's medieval old town, beaches, and annual Medieval Week festival. It is operated by Swedavia, the Swedish state-owned airport operator. Given Gotland's island geography, the airport plays a critical role in the region's connectivity, complementing the ferry services that run between Visby and Nynäshamn or Oskarshamn on the Swedish mainland.
