After the end of the World War II, most organizations in Germany, including sports and football clubs, were ordered to be disbanded by the Allied administration as part of the process of denazification. "BSV" was re-formed as "Sportgeminde Wilmersdorf" and resumed playing in the Berlin league in 1945. They won Gruppe A and then took the league title in a four-team playoff. The Berlin league became the Oberliga Berlin (I) the next season and "Wilmersdorf" earned two consecutive second-place finishes. The club took on its old name for the 1948–49 season and as "Berliner SV" went on to capture divisional titles in 1949 and 1954 before once again going out early in the national playoffs.
