Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大牙齿”，是一种灭绝的鲭鲨科物种，生活在大约2300万年前至360万年前的地质时期，即早中新世至上新世。它曾被认为属于 Lamnidae 科，与大白鲨（Carcharodon carcharias）关系密切。然而，现在被归类于已灭绝的 Otodontidae 家族，其分支在早白垩世就已与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强的掠食者之一，巨齿鲨仅有零散遗骸为人所知，其外观和最大体型仍不确定。科学家们对于它更接近大白鲨的矮胖型、鲸鲨（Rhincodon typus）、抚鲨（Cetorhinus maximus）还是虎鲨属的沙虎鲨（Carcharias taurus）等存在分歧。最近的估算在误差最小的情况下，最大长度可达约20.3米（67英尺），体重可达约103公吨（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)
