Midsayap, officially the Municipality of Midsayap (Maguindanaon: Inged nu Midsayap, Jawi: ايڠد نو ميدسايڤ; Iranun: Inged a Midsayap, ايڠد نو ميدسايۏ; Hiligaynon: Banwa sang Midsayap; Cebuano: Lungsod sa Midsayap; Tagalog: Bayan ng Midsayap), is a 1st class municipality in the Province of Cotabato, Philippines. According to the 2020 census, it has a population of 117,365 people.
Midsayap was derived from a Maguindanaon term which means (Mid) Center and (Sayap) Straw Hat. Midsayap means a straw hat at the center – just like a hill centrally located at the Municipality which slopes through the plains in a shape of a hat. Other version relates that Midsayap came from a Maguindanaon term which means "person wore a straw hat". From 1912 to 1926, Midsayap was then a district of Dulawan and Pikit. Originally, Midsayap was inhabited by Muslims from the descendants of Sultan Ali Bayao from the lineage of Sultan Dipatuan Kudarat I. The seat of their sultanate was established at Libungan Torreta (now part of Pigcawayan).
In 1927, a Philippine Constabulary (PC) Commander assigned in the area, Ist Lt. Catalino Javier, initiated the development of some portions of the municipality. Seeing the natural bounty of the area, he invited settlers from Luzon and Visayas to migrate in the area. The first wave of settlers who dared develop the wilderness was the late Antonio Labasan from Zambales. Among his companions were 23 interrelated families, the Rosete, Almazan, Dumlaos, Flautas, Fernandezes, QuiÑones,Fermils, Fantones and Documos who settled at Sitio Salunayan and Bual . Visayan settlers from Pikit also came to settle at Bual - the place of Datu Guiambangan Dilangalen. The Visayan migrants were headed by Gregorio Bingil, Julio Anito and Tomas Cantoy.
The idea of making Midsayap as a separate political district from the mother municipalities of Dulawan and Pikit was envisioned in 1930 by a group of Christian PC enlisted men who were assigned at Camp Ward. Their efforts, through the support of the deputy governor and military governor was realized in 1936.
