The Palm Jumeirah is an archipelago of artificial islands on the Persian Gulf in Jumeirah, Dubai, United Arab Emirates. It is part of a larger series of developments called the Palm Islands, including Palm Jebel Ali and Deira Islands, which, when completed, will together increase Dubai's shoreline by a total of 520 kilometres (320 mi). It has a population of over 25,000 as of 2022.

An artificial island is an island that has been constructed by humans rather than formed through natural processes. Other definitions may suggest that artificial islands are lands with the characteristics of human intervention in their format process, while others argue that artificial islands are created by expanding existing islets, constructing on existing reefs, or amalgamating several islets together. Although constructing artificial islands is not a modern phenomenon, there is no definite legal definition of it. Artificial islands may vary in size from small islets reclaimed solely to support a single pillar of a building or structure to those that support entire communities and cities. Archaeologists argue that such islands were created as far back as the Neolithic era. Early artificial islands included floating structures in still waters or wooden or megalithic structures erected in shallow waters.
