Opinion polling (popularly known as surveys in the Philippines) for the 2010 Philippine presidential election is managed by two major polling firms: Social Weather Stations and Pulse Asia, and several minor polling firms. The polling firms conducted surveys both prior and after the deadline for filing of certificates of candidacies on December 1, 2009.
The following are results of surveys taken after the last day of filing of certificates of candidacies by the candidates (December 1).
Scores in bold indicate first place, scores in italics are within the margin of error of first place.

Notes:
With the various surveys showing a two-horse race between Noynoy Aquino and Manny Villar, other candidates had expressed doubts on the accuracy of the surveys. Presidential candidate Richard Gordon filed a temporary restraining order before the Quezon City Regional Trial Court, to stop Pulse Asia and SWS from releasing results of pre-election surveys. Gordon said that the research groups used false methodologies and that the 2 survey companies are "stealing the people's minds" and preventing voters from carefully choosing their preferred candidates, particularly those running for president."
