A scupper is an opening in the side walls of a vessel or an open-air structure, which allows water to drain instead of pooling within the bulwark or gunwales of a vessel, or within the curbing or walls of a building.

There are two main kinds of scuppers:

1. Ships have scuppers at deck level, to allow for ocean or rainwater drain-off.{{Cite book |last=Smyth |first=William Henry |url=https://books.google.com/books?id=QeQ2q2ZNg68C&dq=ship+scupper&pg=PA625 |title=The Sailor's Word: A Complete Dictionary of Nautical Terms from the Napoleonic and Victorian Navies |date=2008 |publisher=Fireship Press |isbn=978-1-934757-41-3 |pages=625 |language=en}}
2. Buildings with railed rooftops may have scuppers to let rainwater drain instead of pooling within the railing. Scuppers can also be placed in a parapet, for the same purpose.{{Cite book|url=https://books.google.com/books?id=O9JBAQAAMAAJ&dq=scupper&pg=PA275|title=Sweet's Architectural Catalog File|last=|date=1918|publisher=Sweet's Division, McGraw-Hill Information Systems Company|pages=275|language=en}}
