The Hainan Volcanic Field is a 4,100 square kilometres (1,600 sq mi) volcanic field covering the northern half of Hainan, People's Republic of China.

Although mostly Pleistocene-Holocene in age, minor eruptions have been recorded in the 19th and 20th centuries.

The two best preserved cones (Leihuling and Ma'anshan (马鞍山)) are on an East-West fracture line that contains 30 young cones in the Shishan (石山) and Yongzing regions.

Historically, small fissure eruptions have been recorded from the Lingao and Chengmai areas.

[citation needed] Another small fissure eruption took place from the Nansheling Ridge in the Chengmai area on June 26 (date accurate to within plus or minus 4 days), 1933.
