Port Lympne Wild Animal Park near the town of Hythe in Kent, England is set in 600 acres (2.4 km²) and incorporates the historic mansion and landscaped gardens designed by architect Sir Herbert Baker for Sir Philip Sassoon during World War I.

The estate was purchased in 1973 by John Aspinall to solve lack of space at Howletts Wild Animal Park, and it was opened to the public in 1976. Since 1984 the animal park has been owned by a charity (The John Aspinall Foundation).

Royalty and many other famous people have stayed at the mansion at the centre of the park. The rooms are lavishly decorated and the landscaped gardens take full advantage of the spectacular views of Romney Marsh.

Port Lympne also houses the critically endangered Sifaka and the largest breeding herd of Black Rhinoceros outside Africa. As well as Siberian and Bengal tigers, there are small cats, monkeys, Malayan tapirs, Barbary Lions, which have just given birth to two cubs, African Hunting Dogs and many more rare and endangered species, some of which are on the circular walk. ‘The Palace of the Apes’ is the world’s largest gorillarium and home to a complete family group of gorillas. There is also an open enclosure near some of the rhinos and colobus monkeys.

Lympne ( /ˈlɪm/) is a village situated on the former sea cliffs above the Romney Marsh in Kent. It lies approximately 11 km (6.8 mi) west of Folkestone, 2 miles west of Hythe and 17 km (11 mi) east of Ashford.

In Roman times Lympne was known as "Portus Lemanis", from which (or from the British eponym of which) the English name is derived. It lay at the end of the Roman road from Canterbury, known today as Stone Street. It was the location of a Saxon Shore fort, and, according to a fifth-century source was garrisoned by a regiment originally raised in Tournai in northern Gaul. Its remains are situated at the bottom of the south-facing cliffs; they lie in private land and cannot be visited, though a reasonable view may be obtained from a public footpath above. In Anglo-Saxon times the fort was given the name "Stutfall", meaning "fold in which a stud, or herd, is kept".

St. Stephen's church and Lympne Castle overlook Romney Marsh, the church being significantly older, and close by Lympne Hill figures in the Doctor Syn stories.
