WWT Arundel is one of ten wildfowl and wetland nature reserves managed by the Wildfowl and Wetlands Trust, a nature conservation charity in the United Kingdom.

The 60 acres (24 ha) reserve is situated at the foot of the Offham Hangar, a part of the Arun valley in Arundel, West Sussex, England.

The centre provides a variety of habitats from around the world for its various 'residents' such as its Coastal Creek aviary exhibit with cut-away diving tank.

The site is noted for its summer wildflowers and roosting marsh harriers in winter.

Also available each day are Boat Safari rides through reedbed habitats, driven by WWT wildlife guides.
