Legislative districts of Agusan del Sur

The Legislative districts of Agusan del Sur are the representations of the province of Agusan del Sur in the of the Philippines. The province is currently represented in the lower house of the Congress of the Philippines through its first and second districts.

Prior to gaining separate representation, areas now under the jurisdiction of Agusan del Sur were represented under the Department of Mindanao and Sulu (1917–1935) and Agusan Province (1935–1969). Republic Act No. 4979, approved by plebiscite held simultaneously with the 1967 elections, split the old Agusan Province into Agusan del Norte and Agusan del Sur and provided them each with a congressional representative. In accordance with Section 7 of R.A. 4979, Agusan del Sur elected its separate representative starting in the 1969 elections.

Agusan del Sur was represented in the Interim Batasang Pambansa as part of Region X from 1978 to 1984, and returned one representative to the Regular Batasang Pambansa in 1984. The province retained its lone congressional district under the new Constitution which was proclaimed on 11 February 1987, and elected members to the restored House of Representatives starting that same year.
