Anti-fouling paint is a specialized category of coatings applied as the outer (outboard) layer to the hull of a ship or boat, to slow the growth of and facilitate detachment of subaquatic organisms that attach to the hull and can affect a vessel's performance and durability. It falls into a category of commercially available underwater hull paints, also known as bottom paints.

Anti-fouling paints are often applied as one component of multi-layer coating systems[1] which may have other functions in addition to their antifouling properties, such as acting as a barrier against corrosion on metal hulls that will degrade and weaken the metal,[2] or improving the flow of water past the hull of a fishing vessel[3] or high-performance racing yachts. Although commonly discussed as being applied to ships, antifouling paints are also of benefit in many other sectors such as off-shore structures[4] and fish farms.[5]
