A '''recursive island or lake''', also known as a nested island or lake, is an [[island]] or a [[lake]] that lies within a lake or an island.<ref name="guinnes">{{Cite book|title=2019 Guinness World Records|isbn=978-1-912286-43-0|pages=40–41|title-link=Guinness World Records|last1=Records|first1=Guinness World|date=August 28, 2018}}</ref>
For the purposes of defining [[recursion]], small continental land masses such as [[Madagascar]] and [[Zealandia|New Zealand]] count as islands, while large continental land masses do not. Islands found within lakes in these countries are often recursive islands because the lake itself is located on an island.
