A [[shark barrier]] (otherwise known as a "shark-proof enclosure" or "beach enclosure") is a seabed-to-surface protective barrier that is placed around a beach to separate people from sharks. Shark barriers form a fully enclosed swimming area that prevents sharks from entering.<ref name="abc.net.au">{{cite news|last=Meerman|first=Ruben|title=Shark nets |website=ABC Science|date=16 January 2009|url=http://www.abc.net.au/science/articles/2002/03/07/2116717.htm|access-date=5 January 2017|url-status=live|archive-url=https://web.archive.org/web/20161129034201/http://www.abc.net.au/science/articles/2002/03/07/2116717.htm|archive-date=29 November 2016}}</ref> Shark barrier design has evolved from rudimentary fencing materials to netted structures held in place with buoys and anchors. Recent designs have used plastics to increase strength and versatility.

When deployed in sheltered areas, shark barriers offer complete protection and are seen as a more environmentally friendly option as they largely avoid bycatch. However, barriers are not effective on surf beaches because they usually disintegrate in the swell. Thus, barriers are normally constructed only around sheltered areas such as harbour beaches.<ref>{{cite news|url=http://www.abc.net.au/news/2013-12-22/fact-file-protecting-people-from-shark-attacks/5164882|date=5 January 2015|title=Fact File: Protecting people from shark attacks|website=ABC News}}</ref>
