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".

The setting of most of his novels and short stories is an unnamed land by the sea, apparently far from Europe but with all characters being Western European in name and appearance.

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.
