Gundersweiler is a village and a municipality in the Verbandsgemeinde Nordpfälzer Land and the Donnersbergkreis district, in Rhineland-Palatinate, Germany.

It is located in the valley of Moschelbach in the North Palatine Uplands, southwest of Donnersberg and between Kaiserslautern and Bad Kreuznach.

During the 17th century, robber barons struck the area and the community struggled until armed knights were appointed to guard the road through the Moschelbach valley.

Once Napoleon was defeated, the Congress of Vienna allocated Gundersweiler and the surrounding area to Bavaria, where it remained between 1816 and 1945.

Gundersweiler has its own football team in the form of 'SV Gundersweiler', who play in the 'B-Klasse Kaiserslautern-Donnersberg Nord', on the ninth level of the German football league system.
