Sofía Casanova (30 September 1861 – 16 January 1958) (formally in Spanish: Sofía Guadalupe Pérez Casanova, Polish: Zofia Lutosławska) was a poet, novelist, and journalist, the first Spanish woman to become a permanent correspondent in a foreign country and a war correspondent. 

She was a cultured woman, well-known in the literary circles of the time. In her work she highlighted the human aspect of her chronicles as a correspondent for the newspaper ABC in Poland and Russia, where she reported on the suffering of the civilian population during the wars she covered, adding literary value. Her activity throughout Europe allowed her to experience events such as the First World War, the fall of Czarist Russia, the emergence of the Bolshevik regime, and the Second World War. She wrote for newspapers such as ABC, La Época [es], El Liberal, and El Imparcial [es], for the magazine Galicia, for other Galician publications, and for the international press, such as the Gazeta Polska and the New York Times. Of Catholic and monarchical convictions in the Spanish Civil War, she joined the Francoist ranks. Her long life allowed her to leave behind a broad collection of writings covering all literary genres.
