Hermann Rudolf Schäfer (April 6, 1892, in Remscheid – May 26, 1966, in Bad Godesberg) was a German politician (DDP, FDP, Free People's Party, DP).

During his studies, he became a member of the SBV Nordalbingia Leipzig in 1910 and the Schwarzburgbund association Hercynia Heidelberg in 1911.

During the Second World War he was a captain in the reserve at the General Plenipotentiary for Technical Communications (GBN) in Berlin.

Released from captivity, he joined the German Democratic Party (DDP) in 1920, where he was a member of the Reich Executive Committee from 1925 to 1932.

After the end of the Second World War, Schäfer took part in the founding of the Free Democrats Party in September 1945, which would become the Hamburg regional branch of the FDP.

Schäfer headed the Parliamentary Council commission, which was supposed to examine which of the four candidate cities (Bonn, Frankfurt am Main, Kassel, or Stuttgart) should receive the provisional headquarters of the federal bodies.

The Commission suggested that the Parliamentary Council choose between Bonn and Frankfurt; Kassel and Stuttgart were found unsuitable.
