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. The island is ephemeral, and has been repeatedly built and eroded by successive eruptions in 1852, 1857, 1984, 2006, and 2022.

An eruption in 1984 built a small, temporary island 1500m x 500m, as well as pumice rafts which washed up as far away as Fiji and Australia.

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. In October 2006, it reached almost the same size as it did in 1984, when it was about 0.5 km × 1.5 km (0.3 by 0.9 miles). The island was first seen by the crew of a yacht, who recorded its emergence in their blog. The eruptions produced extensive rafts of pumice, which drifted northeast from the new island. The pumice rafts and new island were imaged by the Aqua satellite in August 2006. Images also revealed several small hot crater lakes on the newly formed island.

The volcano erupted again in September 2022. Eruptions began on 10 September, and by 17 September had built an island with an area of 6 acres and an elevation of 10m above sea level.
