FRM II is a research reactor on the Garching research campus of the Technical University of Munich, in Garching bei München, Bavaria, about 18 km north of Munich. It replaced the university's first research reactor on the same campus.

That first reactor, nicknamed the Atomic Egg, began operation on 31 October 1957 and was shut down in July 2000. Construction of FRM II began with a groundbreaking in August 1996. The reactor was built by Siemens, with highly enriched uranium fuel and a liquid deuterium cold source. It first reached criticality on 2 March 2004, and was handed over to the university for routine operation on 29 April 2005.
