Child of Sorrow (Tagalog: Anak Dalita; subtitled The Ruins) is a 1956 Philippine crime drama-tragedy film directed by Lamberto V. Avellana from a story and screenplay written by Rolf Bayer, with Estrella Alfon and T. D. Agcaoili as story consultants. Set in the slums of Manila, recovering from the aftermath of the Second World War, the story follows Cita, a prostitute with good intentions and Vic, a war hero who served in the Korean War under PEFTOK, living together in the ravaged capital but when they were involved with Cardo's nasty plans, they, along with Father Fidel, join forces to stop him to succeed.

It was theatrically released by LVN Pictures on March 20, 1956, but it did not do well at the box office. Despite the failure, it became one of Avellana's cinematic masterpieces and one of the greatest Filipino films ever made due to its acclaim at the awards and positive reviews and given importance by film critics and scholars in modern times. The film was selected as the Philippine entry for the Best Foreign Language Film at the 29th Academy Awards, but was not accepted as a nominee. The film won the Golden Harvest for Best Film Award at the Asia-Pacific Film Festival in British Hong Kong.
