On Overgrown Paths is the English title of the final novel by Norwegian author and nobel laureate Knut Hamsun.

Written while in police custody after WWII for his outspoken National Socialist sympathies and support of the Quisling government during the German occupation of Norway, 1940-45.

Highly controversial in its day, the narrative structure is of small separate events without obvious links, but differs from his fiction writing only in its claim to be historically and autobiographically true.

Later critics point out that fiction-reality boundaries elide in several of his books and 'OOP' presents some fictional elements as reality.

The novel has been published in German, Italian, Spanish, Icelandic,[3] Hungarian, Serbian (translated by Mirko Rumac; Beograd: LOM, 2011), Bosnian, French,[4] Estonian[5] and Ukrainian.
