Loicia (Aloicia) da Prata or Alucia da Frata (d. after 1268), was the Dogaressa of Venice by marriage to the Doge Reniero Zeno (r. 1252-1268). She was from an influential family of Friuli, which initially a matter of dislike when she became dogaressa. However, Loicia da Prata neutralized this law by her extensive charity as a private person, which she officially conducted not in her position of dogaressa, and which gave her much positive publicity. She founded the Hospital of Sta. Maria on the site originally occupied by that of Doge Pietro Orseolo II., with an Oratory, Oratorio del Crocifisso.
