Ranjitha is an Indian former actress who appeared in Tamil, Malayalam, Telugu and Kannada films during her career. Since 2023, she is known to be serving as the Prime Minister of Kailaasa, a self-proclaimed micronation promoted by Nithyananda.

In 2010, Nithyananda said he was in a relationship with Ranjitha, and officially made the announcement of both of them living together as partners official.

In 2010, Sun TV telecasted a video recording that claimed to show Ranjitha and Nithyananda in a bedroom. The story became viral among news media in Tamil Nadu. They both claimed the video to be fabricated and accused Sun TV of extortion. A Forensic Sciences Laboratory in Bengaluru confirmed that the video appeared to be that of Nithyananda and Ranjitha. Ranjitha filed a complaint with High Court of Karnataka against news channels. Various news channels were ordered to apologize to Ranjitha for violating the complainant's privacy and dignity.

In 2013, she took up sannyasa under Nithyananda.

In 2023, a website associated with Nithyananda displayed the name 'Nithyanandamayi Swami' alongside an image of Ranjitha, bearing the title of the Prime Minister of Kailaasa, a self-proclaimed Hindu state.
