Parteien, die in mindestens drei Landesparlamenten vertreten, werden hier aufgeführt. Der Stichtag ist jeweils der 1. Januar eines jeden Jahres. Auch die Reichstagswahl vom 5. März 1933 ist für die Wahlergebnisse in den einzelnen Ländern mit Ausnahme Preußens von Bedeutung, da sie die Grundlage für die Sitzverhältnisse in den neuen Landtagen bietet. Da die nach dieser Reichstagswahl neu gebildeten Landesparlamente nicht mehr lange existierten und den Anfang des Jahres 1934 nicht mehr erreichten, wird in der letzten Reihe die Jahreszahl 1933 ein zweites Mal, dann aber in Kursivschrift angegeben.
