Legislative district of Agusan del Norte

The Legislative districts of Agusan del Norte are the representations of the province of Agusan del Norte and the highly urbanized city of Butuan in the of the Philippines. The province and Butuan are currently represented in the lower house of the Congress of the Philippines through the first and second congressional districts of Agusan del Norte.

Prior to gaining separate representation, areas now under the jurisdiction of Agusan del Norte 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 providing them each with a congressional representative. In accordance with Section 7 of R.A. 4979, Agusan del Norte elected its separate representative starting in the 1969 elections. The chartered city of Butuan, despite being enumerated as part of the territory of neither successor province, was designated as Agusan del Norte's seat of provincial government and became part of its congressional representation.

Agusan del Norte 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 was grouped with Butuan City and reapportioned into two congressional districts under the new Constitution which was proclaimed on 11 February 1987, and elected members to the restored House of Representatives starting that same year.
