Kowloon Bay is a station on the Hong Kong MTR Kwun Tong line. It is located between Choi Hung and Ngau Tau Kok stations in Kowloon East. The station was opened in 1979.

Kowloon Bay station is one of the five MTR stations on the Kwun Tong line located above ground level, and one of three to be elevated and open-air (the other two being Ngau Tau Kok and Kwun Tong). Due to difficulties in installing platform screen doors (PSDs) in above ground stations, the MTR decided not to install PSDs at this station, instead installing automatic platform gates (APGs) on the station's platforms in 2011. In 2011, the MTR also changed the hue of Kowloon Bay station from black to red.

The headquarters of the MTR Corporation and the depot for the Kwun Tong line are both located at this station. Also located above the depot is Telford Gardens, the first residential property to be developed by the MTR Corporation. Kowloon Bay station is connected to Telford Plaza, a shopping mall located next to Telford Gardens.

John Lok & Partners was chosen to construct the station and adjacent line sections.

Kowloon Bay station opened when the Kwun Tong line became operational on 1 October 1979.
