The Luconia Shoals, divided into the North and South Luconia Shoals, and sometimes known as the Luconia Reefs, are one of the largest and least-known reef complexes in the South China Sea. Some geographers classify the shoals as part of the Spratly Islands.
The shoals lie around 100 kilometres (62 mi) off the Sarawak coast of Borneo, inside the exclusive economic zone of Malaysia and around 2,000 kilometres (1,200 mi) away from Mainland China. The shoals are southwest of the southernmost members of the Spratly Islands. Extending over an area of several thousand square kilometres, both the north and south groups of the shoals are permanently submerged at a depth of 5 to 40 metres (16 to 131 ft) below sea level, with the exception of Luconia Breakers. There are extensive oil and natural gas resources under the seabed in this area, which is also home to various fishes including manta rays, wrasse and grouper. The shoals was also the site where a 150-year-old British cargo vessel known as Viscount Melbourne sank.

The shoals are administered by Malaysia and the Royal Malaysian Navy and Malaysian Maritime Enforcement Agency maintains a 24/7 presence in the area to monitor the shoals. Malaysia's Fisheries Research Institute has conducted studies on the area since 2004.
Malaysia organises an annual International Deep Sea Fishing Tournament on the shoals with participants departing from the Marina May in Miri and heading up to the area for 3 days. The participant who catches the biggest fish are proclaimed the winners of the tournament
On 31 August 2015, amateur marine archaeologist Captain Hans Berekoven with his wife and a team of marine researchers as well Sarawak Museum curator went to the shoals to planting Malaysian flag. Berekoven said the move was important to warn China to back down and urging the Malaysian government to take a serious look into the matter because the site is also a maritime archaeological site of Viscount Melbourne where he was currently on a mission to gather relevant information relating to Sunda Shelf, a sunken site surrounding Southern Asia that could prove a lost civilisation of over 12,000 years old.
In June 2015, Malaysian authorities detected China Coast Guard vessel entering the area, appears to be anchored at the shoals, about 150 kilometres north of Malaysian Borneo—well inside the approximately 400-kilometre exclusive economic zone claimed by Malaysia. The Chinese vessel has been warned to leave the area and is monitored closely by Royal Malaysian Navy. Malaysia lodged a protest over China's incursion into its waters, as the republic’s ships had been in Malaysian waters for more than two years. In a recent statement by Minister in the Prime Minister’s Department Shahidan Kassim, "We have never received any official claims from them (China) and they said the island (Beting Patinggi Ali) belongs to them but the country is 400,000 kilometres (250,000 mi) away.[dubious ] We are taking diplomatic action but in whatever approach, they have to get out of our national waters". The Malaysian government had since sending diplomatic notes every week to protest against the intrusion. There have also been reports that crews aboard the Chinese vessel threatened to shoot local Malaysian fishermen who attempted to fish in the area.
On March 31, 2016, Malaysia summoned the Chinese ambassador in Kuala Lumpur to protest the presence of around 100 Chinese fishing boats at Luconia Shoals. Until March, the Malaysian government rarely rebuked China in public to avoid disturbances to Sino-Malay relations as Beijing emerges as the Malaysian economy's main investors. Kuala Lumpur has “consistently played down China’s activities in our territories,” said Wan Saiful Wan Jan, chief executive of the Institute for Democracy and Economic Affairs, a Malaysian think tank. “This could be to protect our commercial interest, or it could also be to avoid the public...realizing how useless our defenses are.”
