Western Palatinate or West Palatinate (German: Westpfalz) is a sub-region in the west of the Palatinate, a German cultural and historic region in the state of Rhineland-Palatinate. It includes the western part of the Palatine Forest, the central part of the North Palatine Uplands, the West Palatine Moor and the Westrich Plateau. Its former name of "Further Palatinate" (Hinterpfalz), which emerged during the time of Bavarian rule in 1816 and was viewed by the local population as very discriminatory, is only commonly used in the Anterior Palatinate (Vorderpfalz).
The following counties and independent towns or cities lie wholly or partly in the Western Palatinate:County of Kaiserslautern
City of Kaiserslautern
County of Kusel
Town of Pirmasens
County of Südwestpfalz
Town of Zweibrücken
The county of Donnersbergkreis and the old counties of Rockenhausen and Kirchheimbolanden were also counted as part of the Western Palatinate in the widest sense, but are often viewed as an independent region (North Palatinate or Nordpfalz).
A different definition also existed for the division of the police force: the Police District of West Palatinate (Polizeipräsidium Westpfalz) looked after just the western part of Donnersbergkreis county (roughly corresponding to the old county of Rockenhausen) as well as the collective municipality of Meisenheim in the county of Bad Kreuznach as well as the above administrative regions.
