Aleksandr Stepanovich Grinevsky (better known by his pen name, Aleksander Green / Grin (spelling varies in non-Russian literature), Russian: Александр Грин, IPA: [ɐlʲɪˈksandr ɡrʲin] ⓘ, 23 August 1880 – 8 July 1932) was a Russian writer, notable for his romantic novels and short stories, mostly set in an unnamed fantasy land with a European or Latin American flavor (Grin's fans often refer to this land as Grinlandia).

At that time, Grin published mostly short stories; most of his larger works were written after the 1917 October Revolution and enjoyed significant popularity in the first half of the 1920s.

[5] In his book Sculpting in Time, filmmaker Andrei Tarkovsky describes how Grin, when dying of hunger, "went off into the mountains with a home-made bow-and-arrow to shoot some sort of game".

He offers Grin as an example of a poet in the deepest sense: one with "an awareness of the world, a particular way of relating to reality... a philosophy to guide a man throughout his life".

Populated by sea captains, sailors, scientists, travelers, criminals, extravagant aristocrats, childlike girls, elegant villains, and strong-spirited heroes who always stay true to their dreams, Grin's world is often referred to as Grinlandia by fans.
