The Davao de Oro Provincial Board is the Sangguniang Panlalawigan (provincial legislature) of the Philippine province of Davao de Oro, previously known as "Compostela Valley".

The members are elected via plurality-at-large voting: the province is divided into two districts, each having five seats.

The vice governor is the ex officio presiding officer, and only votes to break ties.

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).

Davao de Oro's provincial board also has a reserved seat for its indigenous people (IPMR).
