Cotai Water Jet (Chinese: 金光飛航; Portuguese: Jacto de Água Cotai) is a company that operates high-speed ferry services between Macau and Hong Kong. It is one of the two companies operating high-speed ferry services between the two territories – the other one being TurboJET.

The Taipa Ferry Terminal in Macau is used by this ferry route to enable easy access to The Venetian Macao in Cotai, although it is also chosen by some because of its proximity to Taipa, Cotai, and Coloane in comparison to the Outer Harbour Ferry Terminal (Terminal Marítimo) used by TurboJET on the Macau Peninsula. Cotai Water Jet is a subsidiary of Las Vegas Sands.
