Boksze-Osada ([ˈbɔkʂɛ ɔˈsada]) is a village in the administrative district of Gmina Puńsk, within Sejny County, Podlaskie Voivodeship, in north-eastern Poland, close to the border with Lithuania.

Jewish poet Morris Rosenfeld was born in Boksze-Osada.

One of them enters from the north direction, flowing on the way through Lake Bobruczek, which is a nature reserve of the same name.

At that time, the village, located on the south-western shore of Lake Sejwy Czarne (now Boksze), consisted of seven fibres and was inhabited by eight ploughmen equipped with half-fibres of land.

In addition, they received 2 fibres of land, from which they paid an annual rent of 2 kopecks of Lithuanian pennies.
