Frang Bardhi (Latin: Franciscus Blancus, Italian: Francesco Bianchi) (1606–1643) was an Albanian bishop and author of the early eras of Albanian literature.

He was born in Kallmet or Nënshat in the northern Albanian Zadrima region near Lezhë. He came from a family consisting of many figures high in the hierarchy of the Catholic Church and state officials or military commanders of the Republic of Venice. His uncle was Bishop of Sapa and Sarda. In 1606 he studied theology in Italy. In 1636 he was appointed Bishop of Sapa and Sarda.

Bardhi is remembered as the author of the first Albanian dictionary: Dictionarium latino-epiroticum, Rome 1635 (Latin-Albanian dictionary), comprising 5,640 entries. He also wrote a biography of George Kastrioti Skanderbeg. He claimed that Skanderbeg had Albanian identity attempting to refute assertion of another 17th century Catholic priest that Skanderbeg was Slav. From 1637 on, Frang Bardhi submitted reports in Italian and Latin to the Congregation of the Propaganda Fide in Rome which contain a mine of information about his diocese, about political developments, about Albanian customs and about the structure and position of the Catholic Church in Ottoman-occupied Albania.
