The House of Știrbei, Știrbey or Stirbey is the name of an old Romanian noble family, whose members were once ruling Princes of Wallachia.
The Princely Stirbey family was of Wallachian origin, first documented in the 15th century.
The family emerged in the 19th century as a collateral branch of the House of Bibescu.
Prince Barbu Dimitrie Știrbei was the son of Boyar Dumitrache Bibescu, Palatine of Wallachia (1772–1831), and his wife, Ecaterina Văcărescu (1777–1842).
He was adopted by his relation, one of the most prestigious Oltenian, Vornic Barbu C. Știrbei, the last of the Știrbey line, who made him heir to his wealth and also family name.
