Madalena Matoso is an illustrator. She has a degree in Communication Design from the Faculty of Fine Arts in Lisbon and a postgraduate degree in editorial graphic design from the University of Barcelona. In 1999, she co-founded Planeta Tangerina with three friends. Planeta Tangerina started as a content creation, illustration, and graphic design studio, and in 2004, it began a publishing project.

She has worked on the illustration of various books, including "When I Was Born," "Over Time," "What's There," "Clap Book," "The Boy Andersen's Dictionary," "Mountains," "Where Do We Go When We Disappear?," "We All Do Everything," and "Inside Out," among others. She received the National Illustration Award in 2008 and special mentions in 2006, 2007, 2009, and 2014; the Children's Book Illustration Award at the Amadora Comic Festival in 2008 and 2011; and the SPA/Children and Youth Book Author Award in 2015.
