Friedrich Zollinger, also known as Fritz Zollinger (March 31, 1880 – April 19, 1945) was a German architect, engineer, buildings official and town planner.
He served as city architect in Merseburg, and developed the "Zollinger roof" (a timber lamella roofing system), and the no-fines concreting process.
Fritz Zollinger was not related to the Swiss architect Otto Zollinger (1886–1970) who worked in Saarbrücken from 1924 to 1944.
