The zoo was founded by John Knowles, opening in 1972. It was one of the earliest zoos in Europe to place an emphasis on animal conservation. Within a few years of its establishment, it became an important breeding centre for several species, some (e.g. the Mongolian Wild Horse) already extinct in the wild, others (e.g. the Snow Leopard and Siberian Tiger) close to extinction.
The park is situated in the estate of Marwell Hall, a Grade I listed building originally built in 1320 by Walter Woodlock and largely rebuilt in 1816 by William Long. In the 1500s, the Hall belonged to the Seymour family, and there is a local tradition that Henry VIII married Jane Seymour there. Between September 1941 and March 1944, Cunliffe-Owen Aircraft used the area (part of the Managing Director's personal estate) as an airfield to support the manufacture of military aircraft at its nearby factory in Eastleigh. After the end of World War II, the area was returned to agricultural use until the establishment of the zoo.
In 1977, a giraffe called Victor tore a muscle in his leg, collapsed on his stomach, and was unable to get up. The press suggested that he had slipped while trying to mate and compared his situation to the splits. All attempts to get him on his feet failed, and his plight became a major international news story. Portsmouth Dockyard made a hoist to attempt to raise him onto his feet. He died of a heart attack very shortly afterward in the arms of his keeper Ruth. The publicity turned Marwell into a major tourist attraction, and interest was revived the following summer, when Victor's mate, Dribbles, gave birth to a female calf named Victoria.
In 1999, the zoo lost all of its penguins (22 African and 5 Macaroni) to avian malaria. There were other cases in the UK but Marwell was the only zoo to lose its entire colony, which had arrived only two and a half years before to stock the new Penguin World exhibit. After consulting with experts, the exhibit was restocked with Humboldt penguins, which whilst endangered in the wild, are present in greater numbers in captivity.
In 2003, after constructing a new enclosure for critically endangered Amur leopards, a female leopard (Jade) escaped and fell from a tree to her death after being shot with a tranquilizer dart only days before the official opening of the exhibit. Following a replacement after the death of Jade, in 2005 the first cub born to the new Amur leopard pair, Amirah, escaped into the male's enclosure and was killed by her father. On 18 November 2007, a female Amur leopard cub (named Kiska following a public vote) was born as a result of a European Conservation Breeding Programme.
In 2007, the park was voted in an online poll of Hampshire residents as the place they were most proud of.
Both the park and charity changed their name to "Marwell Wildlife" in April 2009, to promote awareness of conservation work beyond the park. The charity had previously been called the Marwell Preservation Trust, and the park had been Marwell Zoological Park.
The zoo's exhibits include (in addition to those mentioned above in the Animal Exhibits section):
- 449 mammals of 81 species; including tamarins, meerkats, leopards, Amur tigers, Fossa, Giant Anteater, ocelot and Sudan cheetahs.
- 309 birds of 42 species; including Rheas, ibis and flamingoes
- 61 reptiles of 24 species; tortoises and chameleons.
- 31 amphibians of seven species; including salamanders and Poison Dart Frogs
- 18 fish of seven species; including catfish.
- 839 invertebrates of 27 species; including Black Widow Spiders.
The main, current Marwell Wildlife conservation programmes include Managing biodiversity in Hampshire, assisting Grevy's Zebra and its ecosystem; in Kenya, supporting threatened species in Zimbabwe and managing the population of small, vulnerable populations; and reintroducing the scimitar-horned oryx to the Sahara.
The zoo has been involved in reintroducing wild horse, Golden Lion Tamarin, Roan Antelope and Scimitar Oryx to the wild. The oryx was extinct in the wild, but more than 200 calves have been born and reared at the zoo since 1972 and many of these have been released back to the Sahara with animals from Whipsnade Zoo and Edinburgh Zoo.
The charity carries out a range of research and education activities.
The family attraction additionally includes three children’s Playgrounds, various food Kiosks, an African BBQ, and Bushtucker Bites, as well as Picnic areas and tables on Marwell Hall lawn. There is a sheltered area along South Road, next to the Pygmy Hippos.
There is a family friendly hotel situated adjacent to the park.
Marwell Zoo has had notable success breeding various endangered animals including: black and white ruffed lemur (critically endangered), Scimitar-horned Oryx, Amur Leopard (critically endangered) and snow leopard.  In July 2015 a critically endangered Sulawesi-crested macaque baby was born.
