Large aquariums exhibit a large number of species and animals in a large range of tanks. These tend to be public aquariums and may also be oceanariums and dolphinariums, in order to exhibit a wide range of different marine animals for the public.

Only aquariums with a total capacity of more than 10 million litres and/or a tank larger than 5 million litres are included in the list. The list is not necessarily complete; aquariums that may meet the criteria but do not have published sources on their capacity may not be reflected in the list.
