Prahallada Nataka (Odia: ପ୍ରହଲ୍ଲାଦ ନାଟକ Prahallāda Nāṭaka, or simply Rajā Nāṭa) is a traditional play native to the Indian state of Odisha.

It narrates the story of Vishnu's man-lion avatar, Nrusingha or Narasimha, through over 200 songs based on almost 35 ragas of Odissi music.

The play is based on a text by Raja Ramakrusna Chhotaraya, King of Jalantara, a small kingdom in former southern Odisha, now in the Srikakulam district of Andhra Pradesh.

[5] Ramakrusna was the Raja of the small princely state of Jalantara in the southern part of Odisha that borders present-day Andhra Pradesh (the region until North Srikakulam district was part of ancient Kalinga and a large majority of the demography used to be Odia prior to 20th century state formation).

Although attributed to the Raja, researchers agree that the majority of the text was written by the Odissi musician-poet Gourahari Parichha of Paralakhemundi.

While multiple other plays on the same theme exist, Ramakrusna's is generally considered the best example of the routine and was imitated by other Rajas, including Kishore Chandra Harichandan Jagaddeb Ray of Surangi, Padmanabha Narayana Deba of Paralakhemundi, and Ramachandra Suradeo of Tarala.

As of the late 1990s, the play was performed by approximately 57 village theatre companies, due to dwindling audiences.

The complete play, as enacted in royal courts of Odisha's southern gadajatas, often took as long as 7 nights.

Occasionally, Hiranyakasyapa's ministers Biprachitti and Trimastaka, along with the sentry, or duari, occupy the stage throughout the play.

As a mark of respect, the performers maintain ritual purity, which usually means abstaining from non-vegetarian food and liquor.

The ensemble, which typically stands on one side of the mancha, includes Mardala, Mukhabina, Gini, Jhanja, and a Harmonium.
