Dubailand is an entertainment complex being built in Dubai, United Arab Emirates, which is owned by Tatweer (which belongs to Dubai Holding). When announced in 2003 it was one of the most ambitious leisure developments ever proposed anywhere in the world costing 64.3 billion, but development has been severely impacted by global recession and Dubai's financial crisis. The development was put on hold in 2008 and as of late 2011 has not resumed.

The Dubailand project was officially announced on October 23, 2003. Dubailand will have an area of 278 km² (107 sq mi) and include 45 "mega projects" and 200 sub projects. To date, there are currently 22 projects under development. Dubailand is divided into six zones (worlds): Attractions and Experience World, Sports and Outdoor World, Eco-Tourism World, Themed Leisure and Vacation World, Retail and Entertainment World, and Downtown. It will be twice the size of Walt Disney World Resort, and will be the largest collection of theme parks in the world; however, no theme park in Dubailand will surpass Disney's Animal Kingdom (located at Walt Disney World Resort) as the world's largest theme park. Private reaction towards the project has been positive and Dubai has exceeded the $20.9 billion private investment figure it expected on the entire project by collecting approximately $55 billion from the private sector for the first phase.
