The legislative districts of Sarangani are the representations of the province of Sarangani in the Congress of the Philippines.
The province is currently represented in the lower house of the Congress through its lone congressional district.
Prior to gaining separate representation, areas now under the jurisdiction of Sarangani were represented under the Department of Mindanao and Sulu (1917–1935), the undivided province of Cotabato (1935–1967), Region XI (1978–1984) and South Cotabato (1967–1972; 1984–1995).
7228 on March 16, 1992 and its subsequent ratification by plebiscite on November 28, 1992 separated the entire third district of South Cotabato to form the new province of Sarangani.
[1] South Cotabato's former third district automatically became the representation of Sarangani upon its establishment in 1992, but the new province only elected a representative under its own name beginning in 1995.
