The Negros Island Region (NIR) is an administrative region in the Philippines. Covering both the islands of Negros and Siquijor, the region is composed of three provinces: Negros Occidental, Negros Oriental, and Siquijor, as well as the highly urbanized city of Bacolod, which is the most populous in the region. The regional centers are Bacolod and Dumaguete.

The region was originally established on May 29, 2015, comprising the provinces of Negros Occidental, Negros Oriental, and the city of Bacolod, all located on the island of Negros. However, the NIR was abolished on August 9, 2017. Nearly seven years later, the region was re-established on June 11, 2024, this time including Siquijor, an island province southeast of Negros that was previously part of Central Visayas.
