O14 or O-14 is an office skyscraper located in Business Bay in Dubai, United Arab Emirates.

The facade is 40 cm thick and made of an extremely fluid concrete.

The building is held up by the core and exoskeleton so the space inside is largely column free.

O-14 is the winner of the 2009 Silver, Emporis Skyscraper Award.

O-14 also won the 2010 ACEC National Honor Award for Excellence in Engineering Design.
