Sulejki is a village in the administrative district of Gmina Świętajno, within Olecko County, Warmian-Masurian Voivodeship, in north-eastern Poland. It lies approximately 14 km south-west of Olecko and 122 km east of the regional capital Olsztyn. It is located on the northern and eastern shore of Lake Świętajno in the region of Masuria.

History

The origins of the village date back to 1550, when Jakub Dąbrowski bought land to establish a village. The village historically had two equivalent Polish names, Sulejki and Dąbrowskie, the latter of which was derived from the last name of its founder. As of 1600, the population was solely Polish. Siegfried Lenz's book of short stories "So zärtlich war Suleyken" refers to a fictitious village of the same name (as mentioned in a postscript in the same book).
