Bengt af Klintberg (Bengt Knut Erik af Klintberg; born 25 December 1938 in Stockholm) is a Swedish folklorist, ethnologist, and artist who is known for his work on modern urban legends. His work reached a large audience with such books as Råttan i pizzan (The Rat in the Pizza), published in 1986, and Den stulna njuren (The Stolen Kidney) published in 1994.
Klintberg is so widely known for his work on urban legends that the common Swedish word for urban legend for a while was the eponymous "klintbergare" ("klintbergers").
Klintberg was co-host of Folkminnen (Folk Memories), a long-running radio show on Swedish national public radio channel P1, together with Christina Mattsson, at that time the director of the Nordic Museum. The program invited listeners to write letters describing local legends, games, customs or other folklore traditions, as well as encouraging them to ask questions about their origin or significance. After 750 weekly installations, the last broadcast of the program aired in January 2005.
