Provincial elections
All incumbents are expressed in italics.
Governor
Incumbent Governor Berto Uy is running for re-election. A candidate for governor by the name of Roberto Escobido Uy participated and entered in the race. On April 4, 2019, the Commission on Elections issued a resolution making Escobido Uy as a nuisance candidate because it bears the same name and same nickname "Berto" in order to confuse the voters. On November 26, 2020, the Supreme Court of the Philippines upheld COMELEC's decision on disqualifying Escobido Uy.

Incumbent Vice-Governor Senen Angeles is running for re-election.
