Donegall Quay is a public park and greenspace located in Belfast on the River Lagan upstream of the Lagan Weir. It was originally developed in the early 1800s on reclaimed land and became integral to shipping in Belfast Harbour. It is opposite of Queen's Quay.

The Big Fish statue is located on the quay, as is the sculpture Sammy the Seal. Obel Tower is also adjacent to the quay.
