Burkau (German) or Porchow (Sorbian, pronounced [ˈpɔʁxɔf]) is a municipality in the east of Saxony, in the district of Bautzen in Germany.

Burkau is in the northern part of the Bautzen district in a wood rich region in Upper Lusatia.

The inner German motorway A4 between Dresden and Görlitz is near the community and has two direct connections with it.

Nearby in the hills of the western Lusatia there is the source of the Schwarze Elster - one of the most important rivers of this region.

In 1164 the village of Burkau has been mentioned for the first time in document - other sources say it happened some hundred years later in 1312 - that is why the real age of it is still not known.
