Știrbeĭ, Știrbey, or Știrbeiŭ (Francized Alexandre Stirbey; 1837 – March 13, 1895), was a Wallachian-born Romanian aristocrat, politician, businessman and agriculturalist, the son of Barbu Dimitrie Știrbei, Prince of Wallachia, younger brother of George Barbu Știrbei, and nephew of another Prince, Gheorghe Bibescu. After a short career in the French Army, he returned to the United Principalities and served terms in their Assembly of Deputies, inheriting the fortune left by his father. He established pioneering industries around his manorial estates of Buftea and Dărmănești, and became a guest, and sometime host, of literary meetings held by the political club Junimea.
