Öland (UK: , US: ; Swedish: [ˈø̌ːland] (listen); sometimes written Øland in other Scandinavian languages, and often Oland internationally; Latin: Oelandia) is the second-largest Swedish island and the smallest of the traditional provinces of Sweden. Öland has an area of 1,342 square kilometres (518 square miles) and is located in the Baltic Sea just off the coast of Småland. The island has 26,000 inhabitants.

It is separated from the mainland by the Kalmar Strait and connected to it by the 6-kilometre (3+1⁄2 mi) Öland Bridge, which opened on 30 September 1972. The county seat Kalmar is on the mainland at the other end of the bridge and is an important commercial centre related to the Öland economy. The island's two municipalities are Borgholm and Mörbylånga named after their municipal seats. Much of the island is farmland, with fertile plains aided by the mild and sunny weather during summer.

Öland does not have separate political representation at the national level, and is fully integrated into Sweden as part of Kalmar County.
