Saturnina Rizal Mercado de Hidalgo (June 4, 1850 – September 14, 1913; née Rizal Mercado y Alonso Realonda), or simply Saturnina Hidalgo, was the eldest sister of Philippine national hero José Rizal. She was married to Manuel T. Hidalgo, a native and one of the richest persons in Tanauan, Batangas. She was known as Neneng. In 1909, Hidalgo published the first Tagalog/Filipino translation (by Pascual H. Poblete) of her brother's revolutionary novel Noli Me Tángere, thus ensuring Rizal's words became accessible, beyond elite Spanish-speaking circles, to the common Filipino.
