Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon)，意为“Big tooth”，是一种已灭绝的鲭鲨科巨齿鲨，生活在大约2300万年前至360万年前的新近纪早期至中新世晚期之间。它曾被认为属于鲭科（Lamnidae），是大白鲨（Carcharodon carcharias）的近亲。然而，现今被归入已灭绝的 Otodontidae 科，这一科在早白垩纪便与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强的掠食者之一，但巨齿鲨仅以零星遗骸为人所知，其外观和最大体型尚不确定。科学家对其外形更像大白鲨的敦实版本、鲸鲨（Rhincodon typus）、浮鳍鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）谁更接近存在分歧。最新的、误差范围最小的估计显示其最大长度可达约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)
