Zamboanga del Norte occupies the northern portion of the Zamboanga Peninsula — the long arm of Mindanao that extends westward into the Sulu Sea. Its capital, Dipolog City, sits on the Mindanao Sea coast facing the Visayas, while the peninsula's interior rises to forested mountain ranges that form the spine between the north and south coasts.
The province is the largest in the Zamboanga Peninsula region and one of the most geographically diverse in Mindanao — from the coastal lowlands of Dipolog and Dapitan facing the Visayan islands across the Bohol Sea, to the interior mountain forests of the Zamboanga range, to the western coast on the Sulu Sea. Dapitan City, in the province's northern zone, is the site of Jose Rizal's exile.
Jose Rizal was exiled to Dapitan from 1892 to 1896 — four years during which he practised medicine, conducted scientific research, taught local children, and built infrastructure for the town. He documented specimens that were later named after him by European naturalists, oversaw the construction of a water system, and began the romance with Josephine Bracken that he would never complete before his execution.
The 2024 census counted 1,067,067 people in Zamboanga del Norte, in 25 towns and two cities, Dipolog and Dapitan. The province is bordered by the Sulu Sea to the north and west, Misamis Occidental to the northeast and Zamboanga del Sur to the south. Cebuano is the main language, and Chavacano, Subanon, Tausug and Sama are also spoken.
