Narcisa de Leon, Filipino film producer (d. 1966)
Narcisa Buencamino-De León (October 29, 1877 – February 6, 1966) was a Filipino film producer.

Clad daily in the frugal rural dress of the camisón, saya and chinelas, Doña Sisang, as she was widely known, was already a 61-year-old widow when she entered the film industry. Nonetheless, she chartered her family-owned LVN Pictures into a dominant position in post-World War II Philippine cinema. In addition, de Leon was one of the most highly regarded Filipino businesswomen of the first half of the 20th century.Her grandson, Mike de Leon, emerged as a highly acclaimed film director beginning in the 1970s. His 1977 film Kung Mangarap Ka't Magising was dedicated to his late grandmother on the occasion of her birth centenary.In the 1930s was the growth of Philippine cinema, and the new production studios started by her. In the nearby Hacienda Hamady, the Sampaguita Pictures Studio set up shop, while along Justice Pedro Tiangco Tuazon Boulevard in Cubao the LVN Pictures Studio opened in 1936. The studio was named using the initials of the founding families of De Leon, Villonco and Navoa, and continued to operate up to 2005. Now what is left of this historic film studio is a commemorative fountain, dedicated to her as the LVN studio's co-founder and chairperson. The said fountain has been transferred to the Quezon Memorial Circle’s Quezon City Experience Museum, in 2017.
