Plasă (Romanian pronunciation: [ˈplasə], plural plăşi [ˈpləʃʲ]) was a territorial division unit of Romania, ranking below county (judeţ) and above commune. It was headed by a Pretor, appointed by the county Prefect. The institution headed by the Pretor was called Pretură.
The division of counties into plăşi was used starting from the rule of Carol I as Domnitor, throughout the existence of a Romanian Kingdom, and during the first two years of Communist Romania, until they were replaced in 1950 by raions, following the Soviet system.
