Gustav-Adolf Johansson (1912–2011) was a Swedish painter, graphic artist, and cartoonist. Born in Askersund, he was the son of Karl Johansson and Ester Grell, and in 1938 he married Käthie Olsson. Johansson worked professionally as a painter and, in the early 1940s, studied drawing at the ABC School in Stockholm. 

He was awarded a Paris scholarship that enabled him to study at the Académie Julian. He made his debut at the Borås and Sjuhäradsbygden exhibition at Borås Art Museum in 1944 and remained active for decades, with his career spanning into the 21st century. Notably, he participated in the 12th Graphic Triennial at the Stockholm Academy of Fine Arts in 2003, underscoring his long-standing presence in Swedish art.
