The Regionalliga Südwest ('Regional League Southwest') is the fourth tier of the German football league system in the states of Hesse, Baden-Württemberg, Rhineland-Palatinate and Saarland. It is one of five leagues at this level, together with the Regionalliga Bayern, Regionalliga Nordost, Regionalliga Nord and the Regionalliga West.
The league was formed in 2012, when the clubs from the Regionalliga Süd, except those from Bavaria, were joined by the clubs of the Regionalliga West from Saarland and Rhineland-Palatinate.
