Gustav Torgny Lindgren (born 16 June 1938 in Raggsjö, Norsjö, Västerbotten County) is a Swedish writer.
He is the son of Andreas Lindgren and Helga Björk. He studied in Umeå to become a teacher and worked as a teacher until the middle of the 1970's. He was for several years a local politician in the Swedish Social Democratic Party. In the 1980's he converted to the Catholic faith.
Lindgren began his writing career as a poet in 1965. But the big breakthrough wasn't until 1982 with The Way of a Serpent (Swedish: Ormens väg på hälleberget). Lindgren was translated into more than thirty languages and is one of Sweden's most internationally successful contemporary writers. He became a member of the Swedish Academy in 1991.
