Sunning Plaza (Chinese: 新寧大廈) was a 30-storey office building in Causeway Bay, Hong Kong.

This and the adjacent 19-storey residential building Sunning Court (Chinese: 新寧閣) were the first of only two projects in Hong Kong of Chinese-American architect I. M. Pei,[1] the other one being the Bank of China Tower.

There was a large open space around the buildings, creating an "urban oasis" for the dense Causeway Bay area.

A scene of John Woo's movie A Better Tomorrow was filmed at the space before the entrance of Sunning Plaza.

Hennessy Centre, completed in 1981 and owned by the same company, was torn down in 2006 for development of Hysan Place.
