Tacurong City Charter Day, also known as Araw ng Pribilehiyo ng Lungsod ng Tacurong, is observed in Tacurong, Sultan Kudarat, Philippines, every September 18. This special working holiday commemorates the conversion of Tacurong from a municipality to a city, which was confirmed by a plebiscite on this date. Tacurong, a fourth-class component city, is notable for being the most populous area in the province despite having the smallest land area. The city's name is believed to be derived from "talakudong," a traditional head covering worn by locals. The celebration, which lasts for a week, includes various festivities such as street dancing, parades, sports competitions, talent contests, cultural shows, and a beauty pageant. The event highlights the city's rich cultural heritage and community spirit.
