Elisabeta Ana Calea (; ; c. 1367 – 2 August 1439), also spelled Ana Calina () and better known as Lady Calinica (, earlier in Bulgarian: Калиникіѧ, Kalinikĭę), was the second (and most renown) wife of Radu I, a 14th-century Wallachian voivode (nobleman). Ultimately descended from the House of Basarab, she was a Byzantine princess born Caliphië (, Kaliphiē). Calinica was the mother of Mircea I of Wallachia; she outlived her husband by 56 years. Through Calinica the voivodes of Wallachia joined bloodlines with the Basarabs, ancestors of the notorious voivode Dracula.
