Carmen is a first class municipality in the province of Cotabato, Philippines. According to the 2015 census, it has a population of 95,921 people.

Carmen derived its name from a certain Surveyor del Carmen, chief of the Cadastral Survey Party, who in 1924 conducted a survey in the area. During the American period, Carmen and Kabacan belonged to one municipal district under Pikit. It was by virtue of Presidential Proclamation NO. 46 and, was reinforced by Executive Order No. 214 issued by the then President Ramon Magsaysay last November 15, 1956 when Carmen was created as a separate and distinct town of Kabacan.

When created a municipality, it was composed of Thirty Eight (38) barangays. Ten barangays were either claimed or ceded to the two adjacent municipalities, Banisilan and President Roxas. Six by the municipality of Banisilan and four to the municipality of President Roxas. Now, only twenty eight (28) barangays remain in which are presently inhabited by the so-called Tri-people composed of the Christians, the Muslims and Indigenous Peoples belonging to the Manobo-Aromanon ethnic group.

Before it was named Carmen, early inhabitants called this large tract of land "Kalalaw" a Maguindanaon term meaning "jar of water", because legend tells that there was once a big Balite tree with a continuous reservoir of water under its dense foliage, that even in long dry seasons, it had never dried up.

Later on, when early settlers came and cultivated large portions of land in what is now the Poblacion, the whole place was unofficially called "Landing" because of the Landing Field reservation of approximately two hundred (200) hectares. The name "Landing" later on changed to Carmen in honor of del Carmen.

The present Christian in this place are an immigrants from Luzon and Visayas. They are brought here by sheer pioneering spirit inspired by widespread rumors of this "Land of Opportunity and Promise". Their settlement started during the American regime. When the Americans launched their policy of attraction to the Muslims providing advanced technology, economic and educational advancement and the art of government. The first Christian settlers came from Cebu and established settlements at Pikit. Then adventurers followed them from Luzon and Visayas most notably the Ilongos and the Ilocanos who came in great numbers.

During the 2001 Referendum for inclusion to the Autonomous Region in Muslim Mindanao, two (2) out of twenty-eight (28) barangays of Carmen located in its southern territory 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.
