The Santa Justa Lift (Portuguese: Elevador de Santa Justa, pronounced [elɨvɐˈðoɾ ðɨ ˈsɐ̃tɐ ˈʒuʃtɐ]), also called Carmo Lift (Portuguese: Elevador do Carmo, [elɨvɐˈðoɾ ðu ˈkaɾmu]), is an elevator, or lift, in the civil parish of Santa Maria Maior, in the historic center of Lisbon, Portugal. Situated at the end of Rua de Santa Justa, it connects the lower streets of the Baixa with the higher Largo do Carmo (Carmo Square).

Since its construction the lift has become a tourist attraction for Lisbon as, among the urban lifts in the city, Santa Justa is the only remaining vertical (conventional) one. Others, including Elevador da Glória and Elevador da Bica, are actually funicular railways, and the other lift constructed around the same time, the Elevator of São Julião, has since been demolished.
