Petar Hektorović (1487 – March 13, 1572) was a Croatian writer.
Hektorović was born and died in Stari Grad, Hvar. He was a poet and collector of Hvar's fishermen songs, and an important figure of the Renaissance period in Croatian literature. His major work Fishing and Fishermen’s Talk (Ribanje i ribarsko prigovaranje, 1568), is a hybrid genre: simultaneously a travelogue, discourse in fishing, reflexive poem and poetic epistle to his friend Jeronim Bartučević. It is a treasure of Croatian maritime and zoological terminology, which has become incorporated in Croatian standard language. As hybrid as his major work, so was Hektorović's language: chiefly based on a local Čakavian dialect, but amalgamated with the idiom of Štokavian writing poets from Dubrovnik with whom Hektorović has remained in close contact during his lifetime.
