The Venetian Arena (previously known as the Cotai Arena) is an indoor arena located on the premises of The Venetian Macao, on the Cotai Strip, in Macau, China.

It opened in 2007 and has a seating capacity of 14,000.

The facility was known as Venetian Arena from 2007 to 2010, and was renamed the Cotai Arena from 2010 until 2024, when it reverted back to its original name.

It hosts sporting events such as basketball, tennis and boxing, as well as concerts and internationally-televised awards shows.

In November 2024, the venue reopened with its original name, following renovations that added 15 VIP suites, enhanced acoustics, and advanced lighting systems.
