The Pfalztheater is a theatre building and company in the German city of Kaiserslautern, Rhineland-Palatine.
The town's first theatre was built in 1862, financed by Andreas Müller, owner of the Spittelmühle in Kaiserslautern.
It grew to the Städtebundoper during the first decades of the 20th century, in a cooperation with other theatres in the state, especially with Pirmasens and Zweibrücken.
Productions continued there until the building was completely destroyed by bombing on 14 August 1944.
When funding had been raised, the Film-Palast cinema was converted into a permanent replacement for the lost theatre, opening in September 1950.
