Nueva Vizcaya is a landlocked highland province in Cagayan Valley, forming the corridor between the lowlands of Central Luzon and the Cagayan River basin to the north. The province sits along the upper Magat River valley, between the Sierra Madre to the east, the Caraballo Mountains to the south and the Cordillera to the west. It is a province defined by its rivers, its roads, and the mountain communities that have occupied its highland edges for centuries.

The Maharlika Highway passes through Bayombong, making Nueva Vizcaya a transit province between Manila and the Cagayan Valley. Its highland position gives it cooler weather than the Central Luzon plains. The province is home to about 18 indigenous peoples, among them the Ifugao, Gaddang, Isinai, Dumagat, Kalanguya and Bugkalot, whose land use and customs differ from those of the lowland Ilocano settlers.
The Nueva Vizcaya Agricultural Terminal in Bambang supplies vegetables and fruit to neighboring provinces and Metro Manila.
The 2024 census counted 530,106 people in Nueva Vizcaya. It has 15 municipalities: Bayombong is the capital and an education center, Bambang the agricultural hub, Solano the financial district, and Kayapa the summer capital and "vegetable bowl". The province is a major producer of citrus, mainly pomelo, ponkan and oranges.
