Eureka is a rural settlement in the Waikato District and Waikato region of New Zealand's North Island. It is located on State Highway 26, and is surrounded by dairy farmland on a flat plain. There are various explanations for the name. One story suggests William Steele rode out with a syndicate looking for a headquarters, and exclaimed "Eureka I have found it" when he reached the hilltop. Another story suggests "Eureka" is an abbreviation of the first names of the women in the syndicate. The settlement has a war memorial, listing local men who died in World War I and World War II.
