Messini (Greek: Μεσσήνη, before 1867: Νησί Nisi)^[2] is a municipal unit (dimotiki enotita) and the seat town (edra) of the municipality (dimos) of Messini within the regional unit (perifereiaki enotita) of Messenia in the region (perifereia) of Peloponnese, one of 13 regions into which Greece has been divided.^[3] Before 2011 the same hierarchy prevailed, according to Law 2539 of 1997, the Kapodistrias Plan, except that Messenia was a nomos and the Municipal unit was a locality (topiko diamerisma). The dimos existed under both laws, but not with the same constituents.

Messini (modern pronunciation) is not to be confused with its ancient namesake, Messene, located 15 kilometres (9.3 miles) to the north in the shadow of Mount Ithome. Ancient Messene is an equally large but abandoned site of ruins partially occupied by the small village of Mavrommati.
