Malabon–Navotas's at-large congressional district was the combined representation of the Metro Manila municipalities (now highly urbanized cities) of Malabon and Navotas in the lower house of the Congress of the Philippines (1987–2010).
Since 2010, each has been represented separately through the lone congressional districts of Malabon and Navotas.
It included Valenzuela in the defunct legislative district in the Regular Batasang Pambansa from 1984 to 1986 until Valenzuela gained separate representation, leaving the then-municipalities of Malabon and Navotas.
