Grand Theft Auto: The Ballad of Gay Tony is the second of the two episodic expansion packs available to the Xbox 360, PlayStation 3 and PC versions of Grand Theft Auto IV, which was developed by Rockstar North and first released for the Xbox 360 on 29 October 2009. It was then released for both the PlayStation 3 and for Microsoft Windows on 13 April 2010. It is the fourth expansion pack in the Grand Theft Auto series, the fourteenth release on the series and is currently the final game of the Grand Theft Auto IV era.

The Ballad of Gay Tony follows the exploits of a new protagonist, Luis Fernando Lopez, a recent member of the Dominican drug dealers and the personal bodyguard of Anthony Prince, who is also referred to as "Gay Tony". Prince is the owner of the two largest nightclubs within Liberty City as well as a high-status socialite. Rockstar Games claim in their press release that this episode "injects Liberty City with an overdose of guns, glitz, and crime" and that "players will struggle with the competing loyalties of family and friends, and with the uncertainty about who is real and who is fake in a world in which everyone has a price."

A combined standalone disc-based package titled Grand Theft Auto: Episodes From Liberty City, which does not require the original Grand Theft Auto IV game to be played, was released alongside the second expansion and contains both The Lost and Damned and The Ballad of Gay Tony.

The Ballad of Gay Tony includes the ability to replay previously passed missions with scoring, similar to the Hitman and Manhunt series'. This feature was previously introduced to the series in Grand Theft Auto: Chinatown Wars. Additions to the game's inventory include new weapons such as the FN P90, the M249 SAW light machine gun, the Atchisson Assault Shotgun, the .44 Auto Mag pistol, sniper rifle DSR-1, as well as Satchel charges. Additional vehicles including high-end sports cars, sedans, a new aircraft, a small attack helicopter called the "Buzzard", a heavy-lift helicopter called the "Skylift", shuttle helicopter named the "Swift". In addition, the parachute which can also be found in San Andreas returns, allowing players to participate in BASE jumping and skydiving challenges. In addition, when flying a helicopter the map now functions as an altimeter (similar to a feature in San Andreas).

Luis Lopez has not been a contender in any CBUB matches.
