Was Andres Bonifacio declared a Philippine national hero?

No. Andres Bonifacio is one of the Heroes of the country, but he was not declared as a national hero of the country. In fact, despite popular belief to the contrary, nobody, not even Dr. Jose Rizal, has been declared by the Philippine government to be a national hero.

Both Bonifacio and Rizal appear on unofficial lists of national heroes. Rizal is popularly called "the national hero", but since Renato Constantino declared in 1970 that Rizal was a "US sponsored hero" and that the Americans deliberately promoted him over Bonifacio to discourage dissent over their colonization of the Philippines, many now think that Bonifacio is a more important hero than Rizal.

Both Rizal and Bonifacio have national holidays named for them.
