The city was founded in 1938 by Flora Mae Statler, who named it Surprise as she "would be surprised if the town ever amounted to much". Surprise officials previously thought the city was founded by Statler's husband, real estate developer and state legislator Homer C. Ludden, but in 2010 property records were discovered which listed Statler owning the land before she met Ludden. Although there were only a few houses and a gas station on the one-mile (1.6 km)-square parcel of land when it was subdivided to build inexpensive houses for agricultural workers, Surprise has experienced tremendous growth in the years since.
It incorporated into a city in 1960, the townsite being bounded by Greenway Road on the south, Mirage Road on the east, Bell Road on the north, & Dysart Road on the west.
The city is the spring traing home of the Kansas City Royals and the Texas Rangers baseball teams. These Major League Baseball teams use Surprise Stadium for their activities. The city also hosted a Golden Baseball League team in 2005, the Surprise Fightin' Falcons and the Recreation Campus ballpark and is the home city for a team in the Arizona Fall League, the Surprise Rafters. It also hosted ESPN SportsCenter 50 States in 50 Days segment on August 11, 2005.
