Grigore Trandafil (February 4, 1840–February 23, 1907) was a Wallachian-born Romanian magistrate and politician.
Born in Bucharest, he studied law at the University of Paris, obtaining a doctorate.
A close associate of Lascăr Catargiu, he was first elected to the Assembly of Deputies in 1879.
Trandafil was Justice Minister in the cabinet of Gheorghe Manu from November 1890 to February 1891.
Many laws were adopted during his presidency, some of them aiming to improve villagers' material situation, but the measures failed to prevent the 1907 Peasants' Revolt.
