Sofia Yablonska-Oudin (Ukrainian: Софія Яблонська-Уден; fr. Sophie Yablonska-Oudin; 15 May 1907 – 4 February 1971) was a Ukrainian-French travel writer, photographer, and architect. She was born in Habsburg Galicia, but lived itinerantly; she first resided in Galicia, then Russia during the First World War and Russian Civil War, and then in the late 1920s emigrated to Paris. In Paris, Yablonska became a journalist and began travelling the world; she later used these experiences to write three books. Yablonska retired to Noirmoutier in 1950 with her husband and three children (incl. future senator of France: Jacques Oudin) and became an architect.
