Home Reef is a volcanic island atop a submarine volcano in Tonga.

It is located southwest of Vava'u, between the islands of Kao and Late along the Tofua volcanic arc.

[3] After a volcanic eruption started on 8 August 2006, Home Reef emerged as an island; that eruption also spewed into Tongan waters large amounts of floating pumice, which swept across to Fiji about 350 km (220 mi) to the west of the new island.

[6] Images also revealed several small hot crater lakes on the newly formed island.

[14] On the 23 of September, 2023, satellites spotted heat sources and a plume of volcanic gas coming from the island.
