MIMAROPA is one of the two regions of the Philippines having no land border with another region, Eastern Visayas being the other, and is designated as Region IV-B. The name is an acronym that stands for its provinces, which are: Occidental Mindoro, Oriental Mindoro, Marinduque, Romblon and Palawan. Palawan was subsequently moved from MIMAROPA to the more logical Western Visayas, turning the former into MIMARO. There is only one city in the entire region: Calapan City in Oriental Mindoro.

History
Marinduque is an agricultural province, primarily growing rice and coconuts. Fishing is also an important part of the economy. Mining was once an important player in the economy until a mining accident (the Marcopper mining incident) occurred, bringing the industry to a standstill on the island. The provincial government has just recently sued Marcopper's parent company, Placer Dome, for $100 million in damages. It includes Marinduque Island and 24 other islands. Iron, gold, silver, and copper are mined there. There is also a lumbering industry and subsistence farming.
