Katrina Halili (born Maria Katrina Irene Pe Halili on January 4, 1986) is a Filipina actress, commercial model and music producer. She made her screen debut via StarStruck, but did not gain popularity until playing the antagonist roles in Darna, Majika and MariMar and becoming the protagonist in One Night Only, Gagambino and Magdusa Ka.

In May 2009, videos that show compromising encounters between Halili and Dr. Hayden Kho were distributed over the internet without her consent. It was supposed that the person behind the leak of the videos to Internet was a certain Eric Johnson Chua, a close friend and fraternity brother of Hayden Kho. Sen. Ramon Revilla Jr., in his privilege speech, denounced Kho’s acts and would file a case for the removal of Dr. Kho’s license. She is also consulting with the women’s rights group GABRIELA regarding the legal actions that will be placed against Kho. She has since attended a Senate Hearing where she denounced Hayden Kho.Recently she filed a criminal case against the mother of Hayden Kho for libel before the Quezon City Prosecutors Office alleging that the latter made malicious remarks against her. She has also filed against Dr. Kho for violation of Republic 9262 (Anti-Violence Against Women and Their Children).
