Manfred Lindner (born 22 February 1957) is a German physicist and director at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. He conducts basic research in particle and astro-particle physics.

In 1990 he was awarded a Heisenberg Stipendium of the Deutschen Forschungsgemeinschaft (DFG) which he used from 1991 to teach and conduct research at the Universität Heidelberg. In 2016 Manfred Lindner was awarded an honorary doctorate of the KTH Royal Institute of Technology (Kungliga Tekniska Högsksolan, KTH) in Stockholm for important contributions to neutrino physics. The conferment was on November 18, 2016, at an academic ceremony in the Stockholm Concert Hall, followed by a banquet and ball room dancing in the City hall of Stockholm. KTH was founded in 1827 and is Sweden's largest institution of higher education in technology and it awards honorary doctorates to individuals who have done outstanding work while at the same time providing KTH with positive attention. The American Association for the Advancement of Science (AAAS) selected Lindner in 2020 as AAAS Fellow in recognition for distinguished contributions to both theoretical and experimental particle physics.
