Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意思是“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万年至360万年前，涵盖始新世早期至上新世末期的时期。它曾被认为属于Lampnidae科，与大白鲨（Carcharodon carcharias）关系密切。但现在归入已灭绝的 Otodontidae 科，在早白垩纪便与大白鲨分道扬镳。

尽管被认为是史上最大、最强大的掠食者之一，巨齿鲨仅有零散的遗骸可供了解，其外形和最大体长仍不确定。科学家对其体态的推测并不一致，可能更像大白鲨的矮壮版本、鲸鲨（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）。最新、误差范围最小的估算显示，最大身长可达约20.3米（67英尺），体重可达约103吨（114短吨）。

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good  tip, 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)
