O, Capiz, also known as the Capiz Hymn, is the official provincial anthem of the province of Capiz in the Philippines. The hymn, which bested 24 other entries in a province-sponsored competition, was written by Charmaine O. Guartero, a high school music teacher at Filamer Christian University.
The hymn was adopted on June 23, 2006 by an ordinance of the Sangguniang Panlalawigan of Capiz and performed for the first time at the charter aniniversary of the province. The current arrangement, meanwhile, was unveiled on June 25, 2007. According to then-governor Vicente Bernejo, who is currently serving as the mayor of Roxas City, said that in the Capizeños' quest for development, "we need a melody that will inspire us and forge our efforts together to achieve our dream for a better Capiz", describing O, Capiz as a unique expression of what the true Capiz is and what Capizeños really are.
The official video of O, Capiz is available on YouTube and cassette and CD copies of the hymn are being distributed to schools throughout the province.
