Davao Oriental (Cebuano: Sidlakang Dabaw, Filipino: Silangang Dabaw) is a province in the Philippines located in the Davao Region in Mindanao. Its capital is Mati and borders Compostela Valley to the west, and Agusan del Sur and Surigao del Sur to the north.

Davao Oriental is the easternmost province of the country with Pusan Point as the easternmost location. The Philippine Sea, part of the Pacific Ocean, faces Davao Oriental to the east. Part of the province lies on an unnamed peninsula that encloses the Davao Gulf to the west.

The province is the top producer of coconut and copra in the country, earning the province the title Coconut capital of the Philippines.

The present territory of Davao Oriental was covered by the historical region of Caraga, which was under the Sultanate of Maguindanao. The Spaniards established a permanent settlement in the region in 1591, and in 1844, the area was ceded by the Sultanate to Spain. An expedition was sent by the colonial government in Manila in 1847 to control the region, led by the Spaniard Jose Oyanguren, who settled in the town of Davao and organized the surrounding areas into the province of Nueva Guipozcoa in 1849. The province existed until 1858, when the politico-military commandancias of Davao and Bislig were created in its place. Bislig was incorporated into the District of Davao two years later.

In 1903, the colonial American government created the Moro Province comprising several districts, one of which was Davao. The Moro province was converted in 1914 into the Department of Mindanao and Sulu, and its component districts were made into independent provinces.
