Southwestern Tagalog Region in the context of "Southern Tagalog"

In the Philippines, provinces (Filipino: lalawigan or probinsiya) are one of its primary political and administrative divisions. There are 82 provinces at present, which are further subdivided into component cities and municipalities. The local government units in the National Capital Region, as well as independent cities, are independent of any provincial government. Each province is governed by an elected legislature called the Sangguniang Panlalawigan and an elected governor.

The provinces are grouped into 18 regions based on geographical, cultural, and ethnological characteristics. Thirteen of these regions are numerically designated from north to south, while the National Capital Region, the Cordillera Administrative Region, the Southwestern Tagalog Region (Mimaropa), the Negros Island Region, and the Bangsamoro Autonomous Region in Muslim Mindanao are only designated by acronyms.

Marinduque (/ˌmærənˈduːkeɪ/; Tagalog pronunciation: [maɾinˈduke]), officially the Province of Marinduque, is an island province in the Philippines located in Southwestern Tagalog Region or Mimaropa, formerly designated as Region IV-B. Its capital is the municipality of Boac, the most populous in the province. Marinduque lies between Tayabas Bay to the north and Sibuyan Sea to the south. It is west of the Bondoc Peninsula of Quezon province in mainland Luzon; east of Mindoro Island; and north of the island province of Romblon. Some parts of the Verde Island Passage, the center of the center of world's marine biodiversity and a protected marine area, are also within Marinduque's provincial waters.

The province of Marinduque was ranked number 1 by the Philippine National Police and Philippine Security Forces as the 2013 Most Peaceful Province of the country due to its low crime rate statistics alternately ranking with the province of Batanes yearly. Furthermore, for almost 200 years, the province has been home to one of the oldest religious festivals in the country, the Moriones celebrated annually every Holy Week.
