Manila is not part of any province today; it is an independent city within the National Capital Region (NCR), also known as Metro Manila, which itself has no provinces.

Quick answer

  • The city of Manila currently does not belong to any province.
  • It is part of the National Capital Region (NCR) / Metro Manila , a special administrative region that is not composed of provinces but of cities and one municipality.

A bit of background

  • NCR is the smallest administrative region of the Philippines and is uniquely structured: its cities (including Manila) are independent of any provincial government.
  • Historically, there used to be a Province of Manila , but it was abolished in 1901 and its areas were absorbed mainly into the new province of Rizal and the city of Manila.

If someone insists “What province is Manila in?”

When forms or people ask for a “province” for a Manila address, the correct practice is usually to write:

  • City : Manila
  • Province : leave blank or write NCR / Metro Manila (even though NCR is technically a region, not a province).

So in formal geographic and political terms, the answer to “what is the province of Manila?” is: none; Manila is an independent city in the National Capital Region (Metro Manila).
