The following is a list of episodes for the American science fiction drama Eureka which consisted of 77 episodes aired over five seasons. In addition to the regularly televised episodes, there is a short webisode series called "Hide and Seek", which is available on Syfy's Eureka homepage. The creators were able to make minor changes in editing and sometimes dubbed dialogue in later episodes (for instance, they removed the explicit mention of Zoe's first day at school) to minimize audience confusion.
