Andetrium(Albanian: anë deti) meaning seaside, was an ancient city in Illyria, located in modern day Muć or Gornji Muć in the interior of Dalmatia, Croatia.
Andetrium was the location of a Roman cohort in the territory of the Delmatae. During a Roman siege there in AD 9, Arminius's younger brother Flavus lost an eye.
