Sarnowa (German: Sarne, Sarnau, Sarn), formerly a town in its own right, is a historic neighbourhood and administrative district in Rawicz, Poland, located in the northeastern part of the town.

It was mentioned intermittently in various documents over the course of its history, with the first mention of a settlement was as far back as 1065, with another mention in 1110. It was mentioned in the Innocent II's papal Bull of Gniezno in 1136. In 1248 and 1262 it was mentioned in royal documentation, with the latter on 7 June the first mention of Sarnowa as a town, but formally received Magdeburg rights much later, in 1407.

Until 1 January 1973, when it became part of Rawicz by the decision of the Council of Ministers, it was a separate town in its own right.
