Sayo Lamang (Only Yours) is a 2010 Filipino religious-family drama film produced and released by Star Cinema. It is Star Cinema's offering for its 17th year anniversary.

From the director who gave us Tanging Yaman, Laurice Guillen, is back with another heart-warming family drama which teaches us about love, faith and life. Sa Yo Lamang stars Lorna Tolentino, Bea Alonzo, Coco Martin, Enchong Dee and Miles Ocampo. Dianne Alvaro (Bea Alonzo) seems to have a happy family. She and her mom (Lorna Tolentino) just bought a house for them, her younger siblings are doing great at school, and her boyfriend of two years is already preparing for their future together. But everything in her life shatters when her dad, Franco (played by Christopher De Leon), returns after ten years of being with his mistress. More than the irritating presence of Franco, what hurts Dianne the most is how her mom wholeheartedly accepts Franco back to live with them again, and how her siblings allow him to be their father again, as if he never left. Confused and hurt, Dianne does everything to throw Franco out of their lives. But as she succeeds with her plans, she is shocked to learn that their family's problem is more than the return of the man who has hurt her in the past. And thus the start of the journey of Dianne and her family as they discover their family's secrets.
