《龟兔赛跑》是伊索寓言中一个著名的故事。

有一天，乌龟和兔子在谈天，不知不觉说到谁跑得比较快，于是兔子便邀约乌龟比赛跑步。一开始，兔子大幅领先乌龟，但不久后，兔子便开始轻敌，认为乌龟追不上牠，便到路边睡觉。结果乌龟后来赶上，在最后赢了兔子。

The Tortoise and the Hare is one of Aesop's Fables and is numbered 226 in the Perry Index. The account of a race between unequal partners has attracted conflicting interpretations. It is itself a variant of a common folktale theme in which ingenuity and trickery (rather than doggedness) are employed to overcome a stronger opponent.
