Augusto Azzaroli (28 September 1921 - 20 July 2015) was an Italian paleontologist, geologist and stratigrapher.
His family later moved to Florence, where he studied Natural Sciences, graduating in 1945 with a thesis on foraminifera in the surrounding region.
After serving in the Alpine Corps he continued his research, including describing the fossil monkey Macaca majori from Sardinia in 1946.
He also defined the triparite division of the Villafranchian (a time period in the European land mammal ages scheme covering the latter Pliocene and Early Pleistocene) into Early, Middle and Late, which became widely accepted by other researchers.
He also erected the mosasaur genus Goronyosaurus , and was involved in the publication describing the 1 million year old archaic human skull from the Buia locality in Eritrea.
