The renewed popularity of dolphins in the 1960s resulted in the appearance of many dolphinaria around the world, making dolphins accessible to the public.
Criticism and animal welfare laws forced many to close, although hundreds still exist around the world.
In the United States, the best known are the SeaWorld marine mammal parks.

In the Middle East the best known are Dolphin Bay at Atlantis, The Palm and the Dubai Dolphinarium.

Various species of dolphins are kept in captivity.
These small cetaceans are more often than not kept in theme parks, such as SeaWorld, commonly known as a dolphinarium.
Bottlenose dolphins are the most common species of dolphin kept in dolphinariums as they are relatively easy to train, have a long lifespan in captivity and have a friendly appearance.
Hundreds if not thousands of bottlenose dolphins live in captivity across the world, though exact numbers are hard to determine.
Other species kept in captivity are spotted dolphins, false killer whales and common dolphins, Commerson's dolphins, as well as rough-toothed dolphins, but all in much lower numbers than the bottlenose dolphin.
There are also fewer than ten pilot whales, Amazon river dolphins, Risso's dolphins, spinner dolphins, or tucuxi in captivity.
An unusual and very rare hybrid dolphin, known as a wolphin, is kept at the Sea Life Park in Hawaii, which is a cross between a bottlenose dolphin and a false killer whale.

The number of killer whales kept in captivity is very small, especially when compared to the number of bottlenose dolphins, with 60 captive killer whales being held in aquaria as of 2017.
The killer whale's intelligence, trainability, striking appearance, playfulness in captivity and sheer size have made it a popular exhibit at aquaria and aquatic theme parks.
From 1976 to 1997, 55 whales were taken from the wild in Iceland, 19 from Japan, and three from Argentina.
These figures exclude animals that died during capture.
Live captures fell dramatically in the 1990s, and by 1999, about 40% of the 48 animals on display in the world were captive-born.

Organizations such as the Mote Marine Laboratory rescue and rehabilitate sick, wounded, stranded or orphaned dolphins while others, such as the Whale and Dolphin Conservation and Hong Kong Dolphin Conservation Society, work on dolphin conservation and welfare.
India has declared the dolphin as its national aquatic animal in an attempt to protect the endangered Ganges river dolphin.
The Vikramshila Gangetic Dolphin Sanctuary has been created in the Ganges river for the protection of the animals.
