Palawan (/pəˈlɑːwən/, Tagalog: [pɐˈlaː.wan]; officially the Province of Palawan; Cuyonon: Probinsya i'ang Palawan; Tagalog: Lalawigan ng Palawan) is an archipelagic province of the Philippines that is located in the region of Mimaropa. It is the largest province in the country in terms of total area, with 14,649.73 km² (5,656.29 sq mi). The capital and largest city is Puerto Princesa which is geographically grouped with but administered independently from the province. Palawan is known as the Philippines' Last Frontier and as the Philippines' Best Island.

The islands of Palawan stretch between Mindoro island in the northeast and Borneo in the southwest. It lies between the South China Sea and the Sulu Sea. The province is named after its largest island, Palawan Island, measuring 450 kilometers (280 mi) long, and 50 kilometers (31 mi) wide.

In 2019, it was proposed to divide Palawan into three separate provinces, though the proposal was rejected by the local population in a 2021 plebiscite.

The early history of Palawan was determined by a team of researchers led by Robert Bradford Fox. They found evidence in the Tabon Caves that humans have lived in Palawan for more than 50,000 years. They also found human bone fragments, from an individual known as Tabon Man, in the municipality of Quezon, as well as tools and other artifacts.

Two articulated phalanx bones of a tiger, besides another phalanx piece, were found amidst an assemblage of other animal bones and stone tools in Ille Cave near the village of New Ibajay. The other animal fossils were ascribed to macaques, deer, bearded pigs, small mammals, lizards, snakes and turtles. From the stone tools, besides the evidence for cuts on the bones, and the use of fire, it would appear that early humans had accumulated the bones. Additionally, the condition of the tiger subfossils, dated to approximately 12,000 to 9,000 years ago, differed from other fossils in the assemblage, dated to the Upper Paleolithic. The tiger subfossils showed longitudinal fracture of the cortical bone due to weathering, which suggests that they had post-mortem been exposed to light and air. Tiger parts were commonly used as amulets in South and Southeast Asia, so it may be that the tiger parts were imported from elsewhere, as is the case with tiger canine teeth, which were found in Ambangan sites dating to the 10th to 12th centuries in Butuan, Mindanao. On the other hand, the proximity of Borneo and Palawan also makes it likely that the tiger had colonized Palawan from Borneo before the Early Holocene.

Using the work of Von den Driesch, all chosen anatomical features of appendicular elements' anatomical features which were chosen, besides molars, were measured to distinguish between taxa that had close relationships, and see morphometric changes over ages, though not for pigs or deer. For the latter two, cranial and mandibular elements, besides teeth of deer from Ille Cave were compared with samples of the Philippine brown deer (Cervus mariannus), Calamian hog deer (Axis calamianensis), and Visayan spotted deer (Cervus alfredi), and thus two taxa of deer have been identified from the fossils: Axis and Cervus. Remains of pigs were compared with the Eurasian (Sus scrofa) and Palawanese wild boar (Sus ahoenobarbus). It is known that the Eurasian wild boar was imported as a domesticate to the islands from mainland Southeast Asia to the islands during the Terminal Holocene.

Palawan was a major site for the Maritime Jade Road, one of the most extensive sea-based trade networks of a single geological material in the prehistoric world, operating for 3,000 years from 2000 BCE to 1000 CE.^{[not specific enough to verify]}

Palawan is home to several Indigenous groups. The oldest inhabitants are the Palaw'an, Batak, Tagbanwa, and Tau't Bato who are from the interiors and highlands of Palawan, as well as the Calamianes Islands. They traditionally practice animist anito religions. Palawan's coastlines were also settled by later groups that are now collectively known as "Palaweños". Prior to Islamization, the islands of Palawan, Calamian, and parts of Luzon were under the jurisdiction of the nation Sandao (In Chinese records at the 1200s). Sandao was a vassal-state to the more powerful Ma-i nation in Mindoro. Thereafter, groups like the Islamized Molbog people of southern Palawan (possibly originally from Sabah), and the Cuyonon and Agutaynon groups (from the nearby islands of Cuyo and Agutaya settled in.
