Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“大牙齿”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约23到360万年前（始新世早期至上新世时期）。它曾被认为属于鲭鲨科（Lamnidae）并与大白鲨（Carcharodon carcharias）关系密切，但现在被归入已灭绝的 Otodontidae 科，与大白鲨在早白垩纪阶段就分道扬镳。

虽然被认为是有史以来最巨大的、最具威力的掠食者之一，但巨齿鲨的化石证据分散且残缺，其外形和最大体长仍不确定。科学家对它更接近哪种鲨鱼存在分歧：是更像体型更结实的巨白鲨、鲸鲨（Rhincodon typus）、浮头鲨（Cetorhinus maximus）还是沙鲨（Carcharias taurus）的变体。最近一次估算在误差范围最小的情况下，最大身长可达约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)
