Tanging Yaman (international title: A Change of Heart) is a 2000 Philippine religious drama film directed by Laurice Guillen from her written story and screenplay, with Shaira Mella Salvador and Raymond Lee as co-writers of the latter. The film's title came from a liturgical composition by Manoling Francisco, SJ and sung by Carol Banawa.

The film stars Gloria Romero as the loving and devout Lola Loleng, with Johnny Delgado, Edu Manzano, and Dina Bonnevie as her children. It also stars Hilda Koronel, Joel Torre, Cherry Pie Picache, Marvin Agustin, Jericho Rosales, CJ Ramos, Shaina Magdayao, John Prats, Carol Banawa, Janette McBride, and Dominic Ochoa.

Produced and distributed by Star Cinema, the film was theatrically released on December 25, 2000, as one of the official entries for the 26th Metro Manila Film Festival, where it won many awards including Best Picture, Best Actor, and Best Actress. The success of this religious-family drama film was followed ten years later by Sa 'yo Lamang, also directed by Laurice Guillen. In 2014, the film was digitally restored and remastered by ABS-CBN Film Restoration and Central Digital Lab.
