Mafia Wars is a defunct freemium multiplayer social network game created by Zynga.

Mafia Wars won the 2009 Webby Award People's Voice Winner in the Games category.

The game was relaunched on mobile in April 2017 for selected markets, featuring revamped mechanics.

[4] Mafia Wars is set with a choice of playing in New York City or Chicago with the option for players to travel to other locations, such as London, South Africa, and Mexico.

Gameplay was limited by three measurements: Energy, used for completing jobs, as well as Stamina and Health, which were used for fighting or robbing other players.

[6] Mafia Wars was available on Facebook, MySpace, Bebo, Yahoo!, and as a Google Chrome app.

[11] The Zynga trademark application for Mafia Wars sought to cover games for computers and wireless devices.

Davis Elen Advertising ran the campaign, which consisted of fake $25,000 bills glued to the sidewalk promoting "Mafia Wars: Las Vegas".

[15] After the 2010 Haiti earthquake, Zynga issued a special item for three of its games, including the Haitian Drum in Mafia Wars.
