Alsėdžiai (Samogitian: Alsiedē, Polish: Olsiady) is a small town in the Plungė district municipality.

[1] A settlement of Baltic tribes in the territory of the present-day city is said to have existed in the region as early as Mesolithic times.

In June 1941, Jews from the town were kept prisoners in a ghetto,[2] some were killed and some were used as labor slaves.

On December 24, 1941, 24-27 Jewish women and one boy were killed in a mass execution perpetrated by an Einsatzgruppen.

The murderers selected a place by the foot of the hill by the cemetery so the victims couldn't escape.
