Caloocan's 1st congressional district

Caloocan's 1st congressional district, also known as North Caloocan district, is one of the three congressional districts of the Philippines in the city of Caloocan. It has been represented in the House of Representatives of the Philippines since 1987. The district consists mostly of the North Caloocan barangays north of EDSA and Circumferential Road 4: Barangays 1 to 4 of Zone 1, Barangays 77 to 85 in Zones 7 and 8, and Barangays 132 to 177 in Zones 12 to 15. It is currently represented in the 19th Congress by Oscar Malapitan of the Nacionalista Party (NP).

Barangays 178 to 188 in the northern portion of Caloocan were once part of the first district until their separation to form the third district, effective in 2022.
