Seitajärvi (seita: a Sami sacred place + järvi: lake) was a community located in the Savukoski municipality of Finland.
In 1940 the Seitajärvi community included five farming and reindeer enterprises.
On July 7, 1944, Seitajärvi suffered a devastating attack (fi) by Soviet partisans.
Many families of this community relocated to Kittilä in northwest Lapland and nowadays the Seitajärvi people have no standing settlements.
