Legislative districts of Cagayan de Oro City

Congressional Districts of Cagayan de Oro City is the representation of the City of Cagayan de Oro in the Philippine House of Representatives. Prior to being granted its first representation in 1984, the city was part of the representation of Misamis Oriental until 1972 and Region X from 1978 to 1984.

On February 22, 2007, President Gloria Macapagal-Arroyo signed Republic Act 9371 creating the second congressional district in the city by splitting the former lone district into west and the east with the Cagayan de Oro River as the natural boundary.
