Mierczyce is a village in the administrative district of Gmina Wądroże Wielkie, within Jawor County, Lower Silesian Voivodeship, in south-western Poland. It lies approximately south-west of Wądroże Wielkie, north-east of Jawor, and west of the regional capital Wrocław.
Prior to 1945 it was in Germany. After World War II the region was placed under Polish administration and ethnically cleansed according to the post-war Potsdam Agreement. The native German populace was expelled and replaced with Poles.
