The province is currently represented in the lower house of the Congress of the Philippines through its first and second congressional districts.
Prior to gaining separate representation, areas now under the jurisdiction of Davao del Norte were represented under the Department of Mindanao and Sulu (1917–1935) and the historical Davao Province (1935–1967).
The province returned three representatives, elected at-large, to the Regular Batasang Pambansa in 1984.
Apart from restoring the name of the province to Davao del Norte, the passage of Republic Act No.
8470[4] and its subsequent ratification by plebiscite on March 7, 1998, separated the province's eleven eastern municipalities to create the new province of Compostela Valley (now named Davao de Oro).
