Nangyarkoothu is a classical solo performance art from Kerala, traditionally performed by female artists of the Chakkiar community known as Nangiars. With a history spanning over 1,500 years, it is one of Kerala's oldest surviving theatrical forms. Performed in Koothambalams-temple theatres attached to major temples like Vadakkumnathan, Ambalappuzha, and Koodalmanikyam-the art form draws primarily from episodes in Lord Krishna's life, interpreting sacred Sanskrit verses with expressive abhinaya (emotive storytelling), intricate mudras (hand gestures), and stylized movements rooted in Natya Shastra.

Unlike its parent form Kutiyattam, Nangyarkoothu is a strictly solo performance, with the artist enacting multiple characters using distinct changes in posture and voice modulation. The performance is accompanied by the resonant rhythms of the Mizhavu and the gentle chime of Ilathalam (cymbals). While traditionally based on the Bhagavata Purana, the repertoire expanded in 1999 when the acclaimed artist Margi Sathi introduced Ramayana-based narratives.

A royal legend links its origin to King Kulashekara Varman, who granted temple rights to Nangiar performers after marrying one. This royal patronage elevated their status and ensured the continuity of the tradition. Today, Nangyarkoothu continues to thrive as a refined and spiritually rich art form, preserving Kerala's classical legacy.
