Juan Vucetich (1858-1925) was a Croatian-born Argentine anthropologist and police official who pioneered the use of fingerprinting.

He was born as Ivan Vucetic in the Dalmatian region of Croatia then part of the Hapsburg Monarchy. In 1882, he immigrated to Argentina.

In 1891 Vucetich began the first filing of fingerprints based on ideas of Francis Galton which he expanded significantly. He became the director of the Center for Dactyloscopy in Buenos Aries, Argentina. At the time, he included the Bertillon system alongside the fingerprint files.

In 1892 he made the first positive identification of a criminal in a case where Francisca Rojas had killed her two children and then cut her throat, trying to put the blame on an outside attacker. A bloody print identified her as the killer.

Argentine police adapted Vucetich's method of fingerprinting classification and it spread to police forces all over the world. He improved his method with new material and published a book on the subject of fingerprinting. He traveled worldwide and attended scientific conferences to share data.

Juan Vucetich died in Dolores, Argentina.
