The Cavite Provincial Board is the Sangguniang Panlalawigan (provincial legislature) of the Philippine province of Cavite.
The members are elected via plurality-at-large voting: the province is divided into eight districts, two representatives in each district. The candidates with the highest number of votes in each district, depending on the number of members the district sends, are elected. The vice governor is the ex officio presiding officer, and only votes to break ties. The vice governor is elected via the plurality voting system province-wide.
The districts used in appropriation of members is coextensive with the legislative districts of Cavite.
Aside from the regular members, the board also includes the provincial federation presidents of the Liga ng mga Barangay (ABC, from its old name "Association of Barangay Captains"), the Sangguniang Kabataan (SK, youth councils) and the Philippine Councilors League (PCL).
These are the members after the 2022 local elections and 2023 barangay and SK elections:
