Carl Olof "Olle" Hedberg (31 May 1899 in Norrköping, Sweden – 20 September 1974 in Verveln, Östergötland, Sweden) was a Swedish author. Hedberg is known as a probing satirist of the middle class and conventional world in general. His first novel, Rymmare och fasttagare (Prisoner's base), was published in 1930, and from then on would write a novel every year for the next several decades. His works of the 1940s entail a search for religious and moral values. Bekänna färg (Show one’s hand), published in 1947, is considered to be one of his most important novels from this period.
