Nea Kameni is a small, uninhabited Greek island of volcanic origin located in the Aegean Sea, within the flooded Santorini caldera.

Nea Kameni (new burnt) and the neighbouring small island Palea Kameni (old burnt) have formed over the past two millennia through repeated eruptions of dacite lava and ash.

Pliny the Elder reports a new island emerging on July 8, in the year of the consulship of M. Junius Silanus and L. Balbus, thus 19 CE.

The nearly barren island is visited daily by dozens of tourist boats throughout the summer.

Visitors climb a gravel path to reach the top of the 130-meter-high volcanic crater, where it is possible to complete a full circuit of the rim.
