Banisilan is a second class municipality in the province of Cotabato, Philippines. According to the 2015 census, it has a population of 43,677 people.

Located at the northern quadrant of Cotabato Province bounded on the north by the municipality of Wao, Lanao del Sur, on the east to north-east by the municipality of Carmen and Bukidnon, on the west by Alamada, on the south by the municipality of Pikit.

Banisilan is politically subdivided into 20 barangays.

Banisilan has wet and dry seasons, a general characteristic of the Philippian climate.

Banisilan accidentally acquired its name from a type of fresh water shell called the Banisil which were then abundant in the area.

Before Banisilan was created as a separate municipality from Carmen, its mother town, President Ramon Magsaysay signed Proclamation No. 317 dated July 17, 1956 reserving an area of 100,018 hectares of land for a resettlement project which was under the general administration (NARRA) now known as the Department of Agrarian Reform. This resettlement project covers three (3) municipalities and part of these is the North Cotabato Resettlement Project No. 1. As years passed, hundreds of landless and qualified citizens coming from almost all parts of the country were resettled in the area. On March 19, 1959 the first batch of settlers from Panay called SAKADA, headed by Jesus T. Alisasis who become the first Vice Mayor, set foot in Banisilan and in the succeeding months, other tribes from Luzon followed.

During the 2001 Referendum for inclusion to the Autonomous Region in Muslin Mindanao, two (2) out of twenty-eight (28) barangays of Carmen, Cotabato chose to be part of ARMM, but were excluded because they are not connected to the main region of ARMM. During 2010-2016 Administration, the Bangsamoro ideal sprouted and a newly proposed region was in the making. According to the agreements signed by the Moro Islamic Liberation Front and the Administration of Noynoy Aquino, Carmen will be included in Bangsamoro because of the two out of twenty-eight barangays that voted in favor of joining the Muslim region back in 2001. Unfortunately, Bangsamoro was not implemented before the term of Aquino ended. Despite this, the current administration aims to establish a Federal Government, where Bangamoro will be realized into a State of the Philippines wherein Carmen will be included in Bangsamoro.
