The Parliamentary Republic can refer to:

• A republican form of government with a Parliamentary system and a ceremonial head of state or head of state elected by parliament - see Parliamentary republic

A parliamentary republic or parliamentary constitutional republic is a type of republic which operates under a parliamentary system of government - meaning a system with no clear-cut separation of powers between the executive and legislative branches. There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state; with the head of government holding real power, much like constitutional monarchies. Some have fused the roles of head of state and head of government, much like Presidential systems.

Die Parlamentarische Republik ist als Staatsform eine Variante der modernen Republik, bei der das Oberhaupt der Regierung, der Regierungschef, erweiterte Rechte gegenüber dem Staatsoberhaupt, dem Präsidenten besitzt.
