John Österlund (born 21 August 1875 in Stockholm, died 17 February 1953) was a Swedish artist and curator. Österlund studied decorative painting at the senior art and design department of the Technical School, later continuing his education at the Royal Swedish Academy of Fine Arts, where in 1903 he was awarded the Chancellor’s Medal. He then expanded his studies through travels to major European art centers. Shortly afterward, he settled in Uppsala, where he spent much of his career and completed the majority of his works.
