Mirko Basaldella (Udine, 1910 – Cambridge, Massachusetts, 1969) was an Italian sculptor and painter whose work bridged Mediterranean tradition and the international art scene of the mid-twentieth century. Born into a family of artists, he was one of three brothers who trained and first exhibited together with Dino and Afro.
Mirko studied at the academies in Venice and Florence, and in 1928 he first showed his work in Udine alongside his two brothers' paintings. He later attended the Institute of Applied Arts in Monza, where he studied under the sculptor Arturo Martini. In 1934 he settled in Rome, holding his first solo show in 1936 at the Galleria della Cometa. That same year he took part in the Venice Biennale alongside artists linked to the so-called Scuola Romana, including Capogrossi, Ziveri, Janni and Guttuso.
In 1955 he won the first prize for sculpture at the São Paulo Art Biennial. In 1957 he moved to Cambridge, Massachusetts, where Josep Lluís Sert appointed him to direct the Design Workshop at Harvard University. He remained until 1963, when he joined the newly created Department of Visual and Environmental Studies. In 1962 he was elected a member of the American Academy of Arts and Sciences. He died in Cambridge in 1969.
