Dubai Marina (Arabic: مرسى دبي‎, also called Dubai Marina Arabic: دبي مرينا‎) is a district in the heart of what has recently become known as 'new Dubai', in Dubai, United Arab Emirates. It is located on Interchange 5 between Jebel Ali Port and the area which hosts Dubai Internet City, Dubai Media City and the American University in Dubai. The first phase of this project has been completed. The Marina living has become one of the most desirable and sought-after lifestyles in Dubai and has some of the highest property prices for apartments in Dubai. 

The marina is entirely man-made and has been developed by the real estate development firm Emaar Properties of the United Arab Emirates. The marina will contain over 200 high-rise buildings and some supertall skyscrapers, Dubai Marina Towers, The Torch Dubai Marina, Infinity Tower, The Princess Tower, Tamani Hotel Marina, Marina Terrace, Le Rêve (Dubai) and Horizon Tower to name a few, and comprise an area of 4.9 million m² (50 million ft²), which includes the 40 residential and hotel towers of the Jumeirah Beach Residence. Upon completion, it is claimed to be the world's largest man-made marina. Unlike other parts of Dubai there is a publicly accessible foreshoreway around the marina and some sections of public oceanway along the beach with views to Palm Jumeriah. The current largest man-made marina in the world is Marina del Rey in California, USA.
