Otodus megalodon (if the species name, megalodon, derives from Greek and means "large tooth"), commonly known as megalodon or megalodonte, is an extinct [3] species of giant shark that lived from the early Miocene to the early Pliocene, about 23-3,6 millioner år siden (Aquitanisk-Zancleansk), whose large fossil teeth demonstrate that it had a cosmopolitan distribution. In the past it was believed that O. megalodon was a member of the Lamnidae family and a close relative of the great white shark (Carcharodon carcharias), but subsequent studies have reclassified it within the extinct Otodontidae family, a family that separated from the lineage of the great white shark during the early Cretaceous.

Størrelsesestimater for megalodonen varierer avhengig av metoden som brukes, med prognoser for maksimal total lengde mellom 14,2 og 20,3 meter.
