Juliana Josefa Benita Larena Fenollé (16 February 1790, Ejea de los Caballeros, Spain – 1835, Zaragoza, Spain) was a nurse and hero of the Sieges of Zaragoza during the Peninsular War. Larena moved to Zaragoza, Spain at a young age, and was 18 years old when General Lefebvre initiated the French army's first siege on the city in 1808. During the first siege, she worked as a nurse, tending to the wounded on the front line. During the second siege a year later, Larena helped to defend the stronghold located at Cathedral-Basilica of Our Lady of the Pillar, one of the most dangerous areas during the siege.
