Emerald Quay Slipway is a boat launch located on the River Adur at Shoreham-by-Sea, West Sussex, on the western edge of the Emerald Quay residential development. It sits on the north bank of the river and provides open access to the water for trailered boats.

Jet skis are not permitted at this slipway. Optimal launch windows are generally around two hours either side of high tide. The slipway has had a complicated recent history.

It was closed while Environment Agency flood defence work took place, during which the gradient was increased, making it notably steeper than before.

The Emerald Quay Freeholders Group, which owns the slipway, subsequently raised safety concerns about the changes.

A separate feasibility study also noted that the slipway had suffered silting through lack of maintenance, with parking in the immediate area described as very restricted.
