Cesare Emiliani (8 December 1922 – 20 July 1995) was an Italian-American scientist, geologist, micropaleontologist, and founder of paleoceanography, developing the timescale of marine isotope stages, which despite modifications remains in use today.

He established that the ice ages of the last half million years or so are a cyclic phenomenon, which gave strong support to the hypothesis of Milankovitch and revolutionized ideas about the history of the oceans and of the glaciations. He was also the proponent of Project "LOCO" (for Long Cores) to the U.S. National Science Foundation. The project was a success providing evidence of the history of the oceans and also serving to test the hypotheses of seafloor spreading and plate tectonics.

Cesare Emiliani was honored by having the genus Emiliania erected as home for the taxon huxleyi, which had previously been assigned to Coccolithus. He was further honored by receiving the Vega Medal of the Swedish Society for Anthropology and Geography (SSAG) (Swedish: Svenska Sällskapet för Antropologi och Geografi) in 1983, and the Alexander Agassiz Medal of the U.S. National Academy of Sciences in 1989 for his isotopic studies on Pleistocene and Holocene planktic foraminifera.

In his later years, he dedicated a great deal of time to promoting a calendar reform based on the Holocene calendar (HE) concept to eliminate the BC–AD chronology gap caused by the lack of a year 0.
