Leilani Estates is a census-designated place (CDP) in Hawaiʻi County, Hawaii, United States located in the District of Puna. The subdivision was formed in 1964.  The population was 1,560 at the 2010 census,  up from 1,046 at the 2000 census. On May 4, 2018 the subdivision was under voluntary evacuation due to an outbreak of numerous lava vents along the lower East Rift Zone of Kīlauea volcano. By May 6 the count of homes destroyed by lava reached 26.  By May 9, the loss of another home raised the count to 27.  After more homes were destroyed, a mandatory evacuation was ordered by Hawaiʻi Civil Defense by June 1 of all residents from Pomaikai Street eastward, with people found in the area after that date subject to arrest. 
Leilani Estates is located near the eastern tip of the island of Hawaii.  It is 3 miles (5 km) south of Pāhoa and 23 miles (37 km) south of Hilo. It is bordered to the southeast by the Malama Kī Forest Reserve.
Leilani Estates is located directly on a stretch of the lower East Rift Zone of Kīlauea volcano, in lava flow hazard zone 1.  Zone 1 includes the summit and rift zones of active volcanoes—new eruptive vents can spawn anywhere inside this zone. Approximately 10% or 50 square miles (100 km2) out of the 500 square miles (1,000 km2) of Puna have been covered by lava flows since 1790. 
On May 3, 2018, a fissure opened in Leilani Estates, resulting in lava fountaining up to 150 feet (50 m) in the air and spreading over an area 200 yards (200 m) wide.  All inhabitants of Leilani Estates were ordered to evacuate the subdivision.  By May 6 Hawaiʻi County Civil Defence reported that 26 houses in the subdivision had been destroyed after eruptions occurred from 14 separate vents along the rift. By May 9, the destruction of an additional home raised the count to 27.  The rift is a fault in the volcano's structure that runs deep underground, and from the volcano's summit into the sea. The eruption continued until early August, and continued to claim more homes in the subdivision   and beyond it.
