Valenzuela's at-large congressional district

Valenzuela's at-large congressional district was a congressional district for Valenzuela in the Philippines. It was represented in the House of Representatives from 1987 up to its division in 2001. The district was apportioned in 1987, pursuant to the constitution ratified that year, giving the two municipalities their own joint district after having been grouped with Malabon and Navotas from 1984 to 1986. The district was first represented by Antonio Serapio, followed by its last representative Magtanggol Gunigundo I. The district was divided into two districts following Valenzuela's conversion into a highly urbanized city in 1998.
