# Legislative districts of Misamis Occidental

The legislative districts of Misamis Occidental are the representations of the province of Misamis Occidental in the various national legislatures of the Philippines. The province is currently represented in the lower house of the Congress of the Philippines through its first and second congressional districts.

## History

Prior to gaining separate representation, areas now under the jurisdiction of Misamis Occidental were represented under the historical Misamis Province (1907–1931).
The approval of Act No. 3537 on November 2, 1929, split the old province into Misamis Occidental and Misamis Oriental, and provided the new provinces separate representations in the Philippine Assembly. The new province of Misamis Occidental first elected its own representative in the 1931 elections. It also remained part of the eleventh senatorial district which elected two out of the 24-member upper house of the Philippine Legislature when senators were still elected from territory-based districts (1916–1935).
During the Second World War, the Province of Misamis Occidental sent two delegates to the National Assembly of the Japanese-sponsored Second Philippine Republic: one was the provincial governor (an ex officio member), while the other was elected through a provincial assembly of KALIBAPI members during the Japanese occupation of the Philippines. Upon the restoration of the Philippine Commonwealth in 1945 the province retained its pre-war lone district.
Even after receiving their own city charters, Ozamiz, Tangub and Oroquieta remained part of the representation of the Province of Misamis Occidental by virtue of Section 89 of Republic Act No. 321 (June 19, 1948), Section 88 of Republic Act No. 5131 (June 17, 1967), and Section 106 of Republic Act No. 5518 (June 21, 1969), respectively.
Misamis Occidental was represented in the Interim Batasang Pambansa as part of Region X from 1978 to 1984. The province returned one representative, elected at large, to the Regular Batasang Pambansa in 1984.
Under the new Constitution which was proclaimed on February 11, 1987, the province was reapportioned into two congressional districts; each elected its member to the restored House of Representatives starting that same year.
