Asunción Balzola Elorza (July 18, 1942 in Bilbao – June 22, 2006 in Madrid), better known as Asun Balzola, was a Spanish autodidact illustrator, writer and translator. After partially recovering from a severe car crash, she studied painting and graphic arts at the Real Academia de Bellas Artes de San Fernando in Madrid. Balzola worked in advertising and graphic design, in addition to her work in the fine arts. Among other awards, she received the Lazarillo Prize for her illustrations and has twice earned the Spanish National Illustration Prize.
Asun Balzola's illustration style is best known for the use of color blotches and thick lines (frequently painting using a watercolour technique). Her files and library were donated, posthumously, to the Centro de Documentación Infantil of the Central Library at San Sebastián.
