Dodgeball was a location-based social networking software provider for mobile devices. Users text their location to the service, which then notifies them of crushes, friends, friends' friends and interesting venues nearby.Google acquired Dodgeball in 2005 and discontinued it in 2009, replacing it with Google Latitude.

Dodgeball was founded in 2000 by New York University students Dennis Crowley and Alex Rainert. The company was acquired by Google in 2005. In April 2007, Crowley and Rainert left Google, with Crowley describing their experience there as "incredibly frustrating". After leaving Google, Crowley created a similar service known as Foursquare with the help of Naveen Selvadurai.

Dodgeball was available for the cities of Seattle, Portland, San Francisco, Los Angeles, Las Vegas, San Diego, Phoenix, Dallas–Fort Worth, Austin, Houston, New Orleans, Miami, Atlanta, Washington, D.C., Philadelphia, New York City, Boston, Detroit, Chicago, Madison, Minneapolis–St. Paul and Denver.

In January 2009 Vic Gundotra, Vice President of Engineering at Google, announced that the company would "discontinue Dodgeball.com in the next couple of months, after which this service will no longer be available." Dodgeball was shut down and succeeded in February 2009 by Google Latitude.

Dodgeball is any of a variety of games in which players try to hit other players on the opposing team with their own balls while avoiding being hit themselves. This article is about a well-known form of team sport with modified rules that is often played in physical education classes and has been featured in a movie, Dodgeball: A True Underdog Story. In the United States, the game is typically played among children 6-12 in elementary school. However, internationally, the sport has also emerged as a popular middle school, high school and college sport. It is also popular in informal settings and is often played on a playground, in a gym, or in organized recreational leagues.

There are many variations of the game, but generally the main objective of each team is to eliminate all members of the opposing team by hitting them with thrown balls, catching a ball thrown by a member of the opposing team, or forcing them to move outside the court boundaries when a ball is thrown at them.

The number of dodgeballs used in the game often varies, but three to ten is common. Exceptions are usually made if a court is particularly small or if many people participate. More balls generally adds to the amount of action in a game, but can result in stalemate with many blocks. Three is the minimum number of balls to conduct a game with enforced rules. An odd number is generally favourable as one team will necessarily have a majority of balls in possession and should take the offensive role.
