Siedove (Ukrainian: Сєдове; Russian: Седово) is a rural settlement in Kalmiuske Raion, Donetsk Oblast, eastern Ukraine.

[2] The settlement is named after Georgy Yakovlevich Sedov (1877–1914), a Russian Arctic explorer.

Located on the Kriv Spit [uk] on the coast of the Azov Sea, the small city is 60 km east of Mariupol.

Until 1940 it was called Krivaya Kosa (the same name as the spit on which it lies).

Then the village was renamed "Siedove" in honor of the famous polar explorer and hydrographer Georgy Sedov, born there in 1877.
