The Ilocos Sur Provincial Board is the Sangguniang Panlalawigan (provincial legislature) of the Philippine province of Ilocos Sur.
The members are elected via plurality-at-large voting: the province is divided into two districts, each having five seats. A voter votes up to five names, with the top five candidates per district being 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 Ilocos Sur.
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). Ilocos Sur's provincial board also has a reserved seat for its indigenous people (IPMR).
