Kalvøy is an island in Stavanger municipality in Rogaland county, Norway.

The island lies just south of the islands of Lindøy and Hellesøy and together, the three islands form a "neighborhood" within the city of Stavanger. In 2016, the three islands had a total combined population of 26.[1] The island is only accessible by boat. The island of Uskjo lies about to the south (in Sandnes municipality).
