Tibet is a region in East Asia covering much of the Tibetan Plateau that is currently administered by People's Republic of China as the Tibet Autonomous Region and claimed by the Republic of China as the Tibet Area and the Central Tibetan Administration. The CTA uses the snow lion flag of the independent Tibetan state from 1912 to 1951 and the PRC uses its national flag to represent Tibet.

The flag of Tibet (Standard Tibetan: བོད་ཀྱི་རྒྱལ་དར།, lit. 'Tibetan national flag'), also known as the "Snow Lion flag" (gangs seng dar cha), was used by the de facto independent polity of Tibet from 1916 to 1951. It was adopted by the 13th Dalai Lama in 1916 and used until 1959. While the Tibetan flag is illegal in Tibet today, it continues to be used by the Central Tibetan Administration, based in Dharamshala in India.

The Government of the People's Republic of China considers it to be a symbol of separatism; however, the Dalai Lama, the spiritual leader of the Tibetan people, said in recent years that he hoped that Tibet would achieve true autonomy and would not ask for independence. He believes that the symbolism of the flag is similar to that of the Hong Kong regional flag and does not represent the Tibetan independence movement, but the concept of pursuing religious freedom and pursuing national equality and mutual respect.
