The Pfinz is a right tributary of the Rhine in Baden-Württemberg. Its origin is located at the northern edge of the Black Forest near the Straubenhardt borough of Pfinzweiler. Near Durlach it enters the Upper Rhine Plain and continues, splitting into several beds and canals, in northwesterly direction through several towns and villages north of Karlsruhe for example Staffort. The Pfinz discharges into the Rhine near Dettenheim-Rußheim.
