Tibetan literature generally refers to literature written in the Tibetan language or arising out of Tibetan culture. Historically, Tibetan has served as a trans-regional literary language that has been used, at different times, from Tibet to Mongolia, Russia, and present-day Bhutan, Nepal, India, and Pakistan. Today, the term Tibetan literature can also be applied to any work by an ethnic Tibetan person or arising out of Tibetan folk culture; contemporary Tibetan writers sometimes use Chinese, English, or other languages to compose their work.
