Cagayan de Oro's at-large congressional district is an obsolete congressional district that encompassed the entire Cagayan de Oro prior to its 2007 reapportionment that took effect in the same year.[1] It existed from 1984 to 2007, when Cagayan de Oro elected a representative city-wide at-large to the Batasang Pambansa and to the restored House of Representatives.[2] Before 1984 when it was granted its own seat in the regular Batasan assembly as a highly-urbanized city, Cagayan de Oro was represented as part of the multi-member Region X's at-large assembly district for the Interim Batasang Pambansa and was also included in Misamis Oriental's at-large congressional district in the earlier meetings of the Philippine national legislatures from 1931 to 1972. It was last represented by Constantino Jaraula of the Lakas–CMD.[2]
