Happiness Island is an island in the water surrounding Liberty City, officially part of the borough of Algonquin. It is based on the real-life Liberty Island, complete with its own version of the Statue of Liberty, called the Statue of Happiness. The end mission partially occurs on Happiness Island.
Unlike the real-life Liberty Island, Happiness Island has only a light police presence; no reinforcements should arrive (apart from Police Mavericks and Annihilators) as the island is isolated from the mainland, and Predator patrol-boats cannot dock to transport foot police. The island is large enough for the player to escape from a one-star Wanted search radius on foot if they stay out of sight of police, which is useful for players hunting the six pigeons on the island.
Happiness Island is a great location for Team Deathmatch, as one can trap the enemy team on either of the 2 piers. This can easily result in 100-kill games in an Assault Rifles-only match. Trapped opponents may escape using the boats at the piers, however.
- There are six pigeons located on the Statue of Happiness.
- The "Happiness is...land" sweater is obtained on Happiness Island.
- In Grand Theft Auto: Chinatown Wars there are no vehicles on Happiness Island, and no way to take them across. The only way to get them across is to hail a Taxi and set a GPS waypoint for the dealer Osama. Skip the journey, and you have a vehicle on Happiness Island.
