The Kallikratis Programme is the common name of Greek law 3852/2010 of 2010, a major administrative reform in Greece. It brought about the second major reform of the country's administrative divisions following the 1997 Kapodistrias reform.
Named after ancient Greek architect Callicrates, the programme was presented by the socialist Papandreou cabinet and was adopted by the Hellenic Parliament in May 2010. The programme's implementation started with the November 2010 local elections, and was completed by January 2011. It was amended by the Kleisthenis I Programme (Law 4555/2018), which was adopted in July 2018 and implemented in September 2019.
