Koblenz was one of the - at last - three Regierungsbezirke of Rhineland-Palatinate, Germany, located in the north-east of the state. The region was created in 1815 as part of the Prussian Rhineland, becoming part of the new state of Rhineland-Palatinate in 1946. In 1968 the neighbouring Montabaur Region was dissolved and its territory annexed to Koblenz Region.
