Guillermo Roncoroni is an Argentine ufologist who published primarily in the Spanish-language UFO press. His best-known work is his write-up of the 1960 Yacanto case: in 1977, in the magazine UFO PRESS, he published the story of the UFO photograph taken in Córdoba Province by Hugo F. Niotti, an officer of the Argentine Air Force, after interviewing the witness. For a long time, the case remained almost unknown in English-language ufology. Little reliable information is available about Roncoroni's career and further work.
