メガロドン（Megalodon／発音 /ˈmɛɡələdɒn/、MEG-əl-ə-don； Otodus megalodon）は「大きい歯」を意味し、初中新世から鮮新世にかけて約230万年前から360万年前に生息していた絶滅種のサメです。かつてはラミニダ科の一員で、ホオジロザメ（Carcharodon carcharias）の近縁種と考えられていました。ですが現在は絶滅した Otodontidae科に分類されており、ホオジロザメとは初期白亜紀に分岐したとされます。

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good  serrations and enamel, 

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon), meaning "big tooth", is an extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Pliocene epochs. It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias). However, it is now classified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous.

While regarded as one of the largest and most powerful predators to have ever lived, the megalodon is only known from fragmentary remains, and its appearance and maximum size are uncertain. Scientists differ on whether it would have more closely resembled a stockier version of the great white shark, the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus) or the sand tiger shark (Carcharias taurus). The most recent estimate with the least error range suggests a maximum length estimate up to 20.3 meters (67 ft),  weighs up to 103 metric tons (114 short tons)
