Lubang Island is the largest island in the Lubang Group of Islands, an archipelago which lies to the northwest of the northern end of Mindoro in the Philippines. The Lubang Islands are about 150 kilometres (93 mi) southwest of Manila. There are seven islands in the group, The island is divided into two municipalities. The largest settlement is the town of Lubang, west of the island. Its town center is about 8 miles (13 km) northwest of Tilik Port, the only safe anchorage on Lubang Island. The eastern half of the island is covered by the municipality of Looc.
Northwest to southeast the four main islands are Cabra Island, separated by a deep, 3 km wide channel from Lubang Island, then Ambil Island and finally Golo Island. The three smaller islands are Talinas Island, Malavatuan Island and Mandaui Island.
- Cabra Island is mostly wooded and about 3 kilometres (1.9 mi) long, rising to a height of about 60 metres (200 ft). It has a lighthouse at the northwest end of the island.
- Lubang Island is about 125 square kilometres (48 sq mi), being over 25 kilometres (16 mi) in length and up to 10 kilometres (6.2 mi) wide.
- Ambil Island is an extinct volcanic island rising to over 760 metres (2,490 ft) and is about 26 square kilometres (10 sq mi) in area. During the earlier part of the Spanish Colonial Era, Ambil was reported to be in eruption. But when it was climbed by German scientist Carl Semper in the latter part of 19th century, he found no evidence that it has erupted in historical times.
- Golo Island is long, narrow and flat lying, and is about 26 square kilometres (10 sq mi) in area.
The Spanish built a fort on Lubang Island, the San Vicente Bastion, on the western point of the entrance to Port tilig.
After World War II, Lubang Island was where Hiroo Onoda, a Japanese army intelligence officer, hid in the jungles when the Allies reclaimed the Philippines, and engaged in continuous guerrilla warfare against the United States and later against Philippine Commonwealth troops and paramilitary police, refusing to believe the war was over. In March 1974, he was officially relieved of duty, 29 years after the end of the war, making him one of the last Japanese soldiers to surrender.
The islands are administratively part of the province of Occidental Mindoro and are divided into two municipalities: Lubang and Looc. Lubang covers the western half of Lubang Island and Cabra Island, while Looc covers the remaining half of Lubang Island plus Ambil, Golo and the other islands. Looc Proper is divided into three major sections: BonBon, Gitna and Kanluran.
Most of the population resides on Lubang Island, where Tilik Port is located. The main economic activity is fishing in the waters surrounding the islands. However, with the islands fine white-sand coastlines, tourism is growing in economic importance.
