Oo Na... Mahal Na Kung Mahal is a Filipino coming-of-age/romantic comedy film produced by Star Cinema in 1999.
It features the soundtrack "Oo na Mahal na Kung Mahal Kita" performed by the band Frasco and later covered by Parokya ni Edgar (re-titling it as "Wag Mo Na Sana"). It was originally composed by Frasco members Francis Mortiz and Erwin Romulo, contrary to the popular belief that it was Chito Miranda.
