ureka is an American science fiction television series that premiered on Syfy on July 18, 2006. The fifth and final season ended on July 16, 2012. The show is set in a fictional town in Oregon called Eureka. Although in the pilot Eureka was located in Washington State. Inhabited almost entirely by scientific geniuses, most residents of Eureka work for Global Dynamics—an advanced research facility responsible for the development of nearly all major technological breakthroughs since its inception. Each episode features a mysterious accidental or intentional misuse of technology, which the town sheriff, Jack Carter, then solves with the help of town scientists. Each season also features a larger story arc that concerns a particular major event or item.

The series was created by Andrew Cosby and Jaime Paglia and was produced by Universal Media Studios. While initially lacking in critical acclaim, Eureka was a ratings success for the network, averaging 3.2 million viewers during the second half of season three. In 2007, Eureka was nominated for the Emmy Award for Outstanding Visual Effects for a Series, and won the Leo Award for Best Visual Effects in a Dramatic Series. In the United Kingdom the show airs on Syfy and is known as A Town Called Eureka, although it is also shown under its original name on the BT Vision platform.
