Rawa (pronounced: ), older name Roździanka) is a minor river (about 19.6 kilometres in total length) in Silesia, Poland. It is the largest right tributary of the Brynica, itself a tributary of the Przemsza, which in turn is a tributary of the Vistula. The entire length of the Rawa is within the Upper Silesian Metropolitan Union. It has its source in Ruda Śląska and crosses the cities of Świętochłowice, Chorzów and Katowice. Finally in Sosnowiec it joins the Brynica River only several hundred metres before the latter joins with Czarna Przemsza.
The Rawa has lost most of its natural river character, and is now mostly a sewage channel flowing underground. Works have begun in order to restore it back to an ecologically sound water flow.
