There are many reasons why Peoria is one of Arizona’s most desirable destinations. Whether it’s year-round fun at the Peoria Sports Complex (which has been voted the “Best Place in Phoenix to Be Entertained”), touching the stars at the Challenger Space Center, or skimming the waves at Lake Pleasant Regional Park, Peoria offers something for every taste. Of course, Peoria is not just a place to have fun, it’s also a great place to live. The City of Peoria Arizona is Arizona's ninth largest city with an estimated year 2006 population of 138,143. Peoria is located in the Northwest portion of the Valley of the Sun with the state capital of Phoenix and the neighboring city of Glendale to the east, and the retirement community of Sun City to the west.
