Lerøyna or Lerøy is an island in Øygarden Municipality in Vestland county, Norway.

The smaller island of Bjelkarøyna lies just northeast of Lerøyna.

The island has about 30 permanent residents and many vacation cabins.

The island has no road bridge connection with the mainland or other islands, but there is a regular ferry route from Klokkarvik on Sotra, to Lerøyna, to Bjelkarøyna, and then to Hjellestad in Bergen on the mainland.

Øygarden and Bergen municipalities have been making plans to build a road bridge connecting Lerøyna and Bjelkarøyna with a possible connection to the mainland.
