Hans August Osswald (1919–1983) was a Swedish painter, cartoonist, and graphic artist. Born in Örebro, he exhibited individually at Louis Hahne’s art store in Stockholm in 1947, followed by solo shows in Örebro and Kalmar. He also participated in group exhibitions with the Dalarnas Art Association, ABF in Ludvika, and in traveling exhibitions with Grafik och skulptur and Konstfrämjandet.

Osswald’s art consisted primarily of abstract works featuring primitive motifs of fish and birds, executed in drawings, colored woodcuts, or gouache. Alongside his own creations, he worked as a book illustrator. His works are represented at Malmö Museum and Eskilstuna Art Museum.
