Causeway Bay (Chinese: 銅鑼灣; Cantonese Yale: Tùnglòwāan) is an underground metro station on the MTR network in Hong Kong.

Named for the Causeway Bay area and its abundant shopping centres, the station serves various malls including Hysan Place, Sino Plaza, Sogo, and the nearby Victoria Park.

The station consists of two separate concourses situated atop two platforms stacked vertically due to geographical constraints and has 6 exits.
