Hasslö

Hasslö is an island in the municipality of Karlskrona, Sweden. As of 2003, its population was 1606.

For many years, the Swedish navy's activities on Hasslö meant that foreigners' access to the island was restricted, but that is no longer true. Hasslö is famous for its fish, and fishing has historically been the main livelihood. A famous fishing site on Hasslö is the 'Rallbryggan'.

Hasslö is a flat island and most of the people live near the coast.

Hasslö is connected to the mainland via the Hasslö Bridge.
