Eugen Bejinariu (Romanian pronunciation: [e.u'd??en be?i'narju]; born 28 January 1959, Suceava) is a Romanian politician and member of the Social Democratic Party (PSD).
He served as interim prime minister of Romania between December 21 and 28, 2004, when prime minister Adrian Nastase, who had just been defeated in presidential elections by Traian Basescu, resigned and became President of the Chamber of Deputies.
Bejinariu was appointed as interim prime minister at the request of resigning prime minister, Adrian Nastase, and confirmed by the new president Traian Basescu to hold the office until a new prime minister was named.
Bejinariu was the minister of government coordination in Nastase's cabinet, joining the government after a long stint as chairman of Romania's State Protocol Department (RAPPS).
He was replaced as prime minister on December 28, 2004 by Calin Popescu-Tariceanu.
