Kvitsøy or Kvitsøya is the main island in Kvitsøy municipality in Rogaland county, Norway.

The main population centre on the island is the village of Ydstebøhamn on the southern coast.

The village of Ydstebøhamn has a ferry quay which receives regular ferries from the town of Skudeneshavn on the island of Karmøy across the Boknafjorden to the north, and to the village of Mekjarvik in Randaberg municipality across the Kvitsøyfjorden on the mainland to the south.

The planned Rogfast undersea tunnel will connect Kvitsøy to the mainland to the north and south as part of the government's goal of providing a ferry-free European route E39 highway along the west coast of Norway.
