Glendale Arizona's Westgate City Center is a 223-acre (0.90 km2), mixed-used development that will ultimately include up to 8,000,000 square feet (740,000 m2) of shopping, dining, entertainment, high-end condominiums, parks, and office space. It is anchored by Jobing.com Arena, home of the Phoenix Coyotes, and adjacent to the University of Phoenix Stadium, home to the Arizona Cardinals and Super Bowl XLII.

Development of Westgate City Center began with the construction of the Jobing.com Arena, then referred to as the Glendale Arena. Construction of the Arena was completed in late 2003 and it hosted its first NHL game on December 27 of that same year, while construction of the remainder of Westgate's Entertainment District began in October 2005, opening one year later.

The project has been split into multiple phases to facilitate construction and development. Phase I, the initial 510,000-square-foot (47,000 m2) development, opened to the public on November 17, 2006 in limited fashion with only a few restaurants and a sports merchandise store, with other retailers, restaurants and a 20-screen theater opening in the following weeks. Phase I also includes an upmarket 12-story Renaissance Hotel completed in mid 2007, and a convention center, as well as outdoor entertainment facilities. Westgate City Center is now home to more than 30 bars and restaurants as well as a vibrant mix of national, regional and local retailers.

Phase II will add an estimated 436,000-square-foot (40,500 m2) retail destination center and 105,000 square feet (9,800 m2) of "neighborhood retail" to be integrated into a 440-unit residential district..

The development of future phases will be contingent upon market demand and is yet to be scheduled, although estimated completion dates range from 2010 to 2015 at a potential total cost of $1 billion.

Westgate was built around Jobing.com Arena, which is its primary attraction. Although not a part of the development, the University of Phoenix Stadium, home of the Arizona Cardinals, is located directly adjacent to the development. Management of both Westgate and the University of Phoenix Stadium have cited their proximity as creating a synergistic boom to the area. Although not within Westgate's borders, the camping, fishing, and hunting retailer Cabela's can be found adjacent to the development and draws visitors to the Westgate City Center each year.

Adjacent to the Jobing.com Arena and central to the project is WaterDance Plaza, and events plaza featuring a Belagio-style, "dancing" water feature and a massive complex of outdoor signage. Cooperating with media giant Clear Channel Communications, the development includes 30 large electronic signs, some in excess of 100 feet (30 m). The agglomeration of electronic signage and media boards, said to be the largest "Media & Signage District" west of Times Square has earned it the nickname "Times Square of the West"

WaterDance also features a 60,000-US-gallon (230,000 l; 50,000 imp gal) "dancing fountain" display, costing some $5 million to construct. The fountain was inspired by the more elaborate display at the Bellagio casino in Las Vegas and has been described as "Bellagio-esque."

As home of the Jobing.com Arena, a number of events are held at Westgate City Center. Often visitors waiting for events such as concerts, conventions, and sports held in the arenas will spend time in Westgate whilst waiting for the events to begin. The Center itself is the host of a number of independent events. Westgate hosted its first major event, Westgate Rocks on December 31, 2006, the first premiere New Year's block party to be featured on Phoenix's west side. An estimated 7,500 people attended the party.. In addition, Westgate is home to the annual AVP pro volleyball tournament, Action Sports extreme sporting events, Miller Lite Tailgate Parties before Cardinals home games, monthly farmers markets, live entertainment in Fountain Park, and high-end art exhibitions.

Westgate has also become home to a number of smaller-scale block parties to cheer on local American Idol contestant Jordin Sparks. Recent block parties related to the show have drawn over 700 people.
