The Nāṭya Shāstra (Sanskrit: नाट्य शास्त्र, Nāṭyaśāstra) is a Sanskrit treatise on the performing arts. The text is attributed to sage Bharata, and its first complete compilation is dated to between 200 BCE and 200 CE, but estimates vary between 500 BCE and 500 CE.

The text consists of 36 chapters with a cumulative total of 6,000 poetic verses describing performance arts. The subjects covered by the treatise include dramatic composition, structure of a play and the construction of a stage to host it, genres of acting, body movements, make up and costumes, role and goals of an art director, the musical scales, musical instruments and the integration of music with art performance.

The Nāṭya Śāstra is notable as an ancient encyclopedic treatise on the arts, one which has influenced dance, music and literary traditions in India. It is also notable for its aesthetic "Rasa" theory, which asserts that entertainment is a desired effect of performance arts but not the primary goal, and that the primary goal is to transport the individual in the audience into another parallel reality, full of wonder, where they experience the essence of their own consciousness, and reflect on spiritual and moral questions. The text further inspired secondary literature such as the 10th century commentary Abhinavabharati – an example of a classic Sanskrit bhasya ("reviews and commentaries") – written by Abhinavagupta. In April 2025, the Nāṭya Shāstra manuscript was added to UNESCO’s Memory of the World Register.

The title of the text is composed of two words, "Nāṭya" and "Shāstra". The root of the Sanskrit word Nāṭya is Nata (नट) which means "act, represent". The word Shāstra (शास्त्र) means "precept, rules, manual, compendium, book or treatise", and is generally used as a suffix in the Indian literature context, for knowledge in a defined area of practice.

Performance arts and culture

Let Nāṭya (drama and dance) be the fifth vedic scripture.
Combined with an epic story,
tending to virtue, wealth, joy and spiritual freedom,
it must contain the significance of every scripture,
and forward every art.

The composition date of Nāṭya Shāstra is unknown. Estimates vary between 500 BCE to 500 CE. The text may have started in the 1st millennium BCE, expanded over time, and most scholars suggest, based on mention of this text in other Indian literature, that the first complete version of the text was likely finished between 200 BCE to 200 CE. The Nāṭyaśāstra is traditionally alleged to be linked to a 36,000 verse Vedic composition called Adibharata, however there is no corroborating evidence that such a text ever existed.

The text has survived into the modern age in several manuscript versions, wherein the title of the chapters varies and in some cases the content of the few chapters differ. Some recensions show significant interpolations and corruption of the text, along with internal contradictions and sudden changes in style. Scholars such as PV Kane state that some text was likely changed as well as added to the original between the 3rd to 8th century CE, thus creating some variant editions, and the mixture of poetic verses and prose in a few extant manuscripts of Natyashastra may be because of this. According to Pramod Kale, who received a doctorate on the text from the University of Wisconsin, the surviving version of Natya Shastra likely existed by the 8th-century.
