Surat Kecil untuk Tuhan (phrasal translation: A Diary of Letters to God) is a 2011 Indonesian biographical drama film directed by Harris Nizam.

Keke (Dinda Hauw) is a young girl with a loving father (Alex Komang) and mother, as well as loyal friends.

After undergoing twenty-five sessions of chemotherapy, the once healthy and beautiful Keke finds herself sickly and bald, with a disfigured face.

Surat was based on the true story of Gita Sesa Wanda Cantika, a 15-year-old student who was diagnosed with and on 25 December 2006 died of the first reported case of Rhabdomyosarcoma in Indonesia.

[5] Indah Setiawati, writing for The Jakarta Post, described Surat as a "heartwarming movie about spirit, family and friendship" that would make audiences cry, despite some technical deficiencies.
