The Regionalliga Südwest was the second-highest level of the German football league system in the southwest of West Germany from 1963 until the formation of the 2.

Originally only the winners, later also runners-up of this league were admitted to the promotion play-off to the new Bundesliga, which was staged in two groups of originally four, later five teams each with the winner of each group going up.

The bottom three clubs in the league, nominally the relegated teams in a normal season, were barred from entry to the 2.

[1] Points table: In 1994, the Regionalligas were reintroduced, this time as the third tier of German Football.

The teams from the southwest were however integrated into the new Regionalliga West/Südwest with the clubs from Nordrhein-Westfalen.

Liga the southwestern clubs will again move, into the new Regionalliga West and again be with the teams from Nordrhein-Westfalen.
