Frank Asaro (narozen jako Francesco Asaro; 31. července 1927 – 10. června 2014) byl americký chemik, který se proslavil zejména jako spoluobjevitel „iridiové stopy“ v jílové vrstvě horniny z období přelomu křídy a paleocénu (hranice K-T nebo nověji K-Pg, datovaná do doby před 66 miliony let). Stal se tak roku 1980 spolu s Luisem Alvarezem, Walterem Alvarezem a Helem Michelovou tvůrcem impaktní teorie o vyhynutí dinosaurů - myšlenky, že vymírání na konci křídy způsobil dopad velké planetky z vesmíru. Asaro byl od 50. let 20. století specialistou na datování archeologických a paleontologických objektů a nálezů (hornin, soch, keramiky apod.) za pomoci moderních chemicko-fyzikálních laboratorních metod. Po celý svůj život žil a působil v Kalifornii a jeho jméno je spojeno s Kalifornskou univerzitou v Berkeley. (cs) Frank Asaro (born Francesco Asaro, July 31, 1927 – June 10, 2014) was an Emeritus Senior Scientist at the Lawrence Berkeley National Laboratory associated with the University of California at Berkeley. He is best known as the chemist who discovered the iridium anomaly in the Cretaceous–Paleogene boundary layer that led the team of Luis Alvarez, Walter Alvarez, Frank Asaro, and Helen Michel to propose the Asteroid-Impact Theory, which postulates that an asteroid hit the Earth sixty-five million years ago and caused mass extinction during the age of the dinosaurs.
