Which genre is sometimes described as a "desert island story"?

Robinsonade is a literary genre that takes its name from the 1719 novel "Robinson Crusoe" by Daniel Defoe. The success of this novel spawned so many imitations that its name was used to define a genre, which is sometimes described simply as a "desert island story" or a "castaway narrative".

In a robinsonade, the protagonist is suddenly isolated from the comforts of civilization, usually shipwrecked or marooned on a secluded and uninhabited island. He must improvise the means of his survival from the limited resources at hand.

The word "robinsonade" was coined by the German writer Johann Gottfried Schnabel in the Preface of his 1731 work "Die Insel Felsenburg" ("The Island Stronghold").
