The Asiatic lion, also known as the Persian lion, is a population of Panthera leo leo that today survives in the wild only in India. Since the turn of the 20th century, its range has been restricted to Gir National Park and the surrounding areas in the Indian state of Gujarat. Historically, it inhabited much of southwest Asia to northern India.
The first scientific description of the Asiatic lion was published in 1826 by the Austrian zoologist Johann N. Meyer, who named it Felis leo persicus. On the IUCN Red List, it is listed under its former scientific name Panthera leo persica as Endangered because of its small population size and area of occupancy. Until the 19th century, it occurred in Saudi Arabia, eastern Turkey, Iran, Mesopotamia, Pakistan, and from east of the Indus River to Bengal and the Narmada River in Central India.
The population has steadily increased since 2010. In May 2015, the 14th Asiatic Lion Census was conducted over an area of about ; the lion population was estimated at 523 individuals, comprising 109 adult males, 201 adult females and 213 cubs. In August 2017, surveyors counted 650 wild lions. In June 2020, an estimation exercise counted 674 Asiatic lions in the Gir forest region, an increase of 29% over the 2015 census figure.
The lion is one of five pantherine cats native to India, along with the Bengal tiger (P. tigris tigris), Indian leopard (P. pardus fusca), snow leopard (P. uncia) and clouded leopard (Neofelis nebulosa).
Felis leo persicus was the scientific name proposed by Johann N. Meyer in 1826 who described an Asiatic lion skin from Persia.
In the 19th century, several zoologists described lion zoological specimen from other parts of Asia that used to be considered synonyms of P. l. persica:
Felis leo bengalensis proposed by Edward Turner Bennett in 1829 was a lion kept in the menagerie of the Tower of London. Bennett's essay contains a drawing titled 'Bengal lion'.
Felis leo goojratensis proposed by Walter Smee in 1833 was based on two skins of maneless lions from Gujarat that Smee exhibited in a meeting of the Zoological Society of London.
