Sven (Svän) Fritiov Teodor Grandin (1906–1982) was a Swedish painter whose work encompassed floral still lifes, figure motifs, and landscapes. Born in Borås, he first worked as a textile worker and sailor before turning to art. Largely self-taught, he refined his practice during study trips to Paris in 1938–1939 and 1946.

Grandin debuted at the Borås and Sjuhäradsbygdens Konstförenings Höstsalong in 1936 and subsequently exhibited in solo and group shows in Stockholm, Gothenburg, and Skara. His art reflects a lyrical engagement with natural and figurative subjects, and he is represented at Borås Art Museum.
