Illa de Tagomago is a private island off the east coast of Ibiza belonging to Spain.

The island is rocky, with a port and a lighthouse in the extreme southeast.

The Tagomago lighthouse was built in 1913 and is a landmark in the shipping routes from Ibiza to Palma de Mallorca and Barcelona.

It is 86.3 m above sea level, and its height is 20.4 m.[1] The island is privately owned by a Spanish family, and has a small tourist facility that politicians and celebrities frequently visit.

Tago Mago, the second studio album by German krautrock band Can, was named after the island.
