Prithvi Rajan is an Indian actor who has worked in Tamil films. His father is Pandiarajan, a renowned actor.

He made his debut in Kaivantha Kalai (2006), directed by his father Pandiarajan, which received average reviews from reviewers. A critic wrote that Prithvi Rajan “makes his debut, does a convincing job, and has his father’s mannerisms.” His following film, Naalaiya Pozhuthum Unnodu (2007), a romantic love story starring Karthika Adaikalam, had a considerably lower-key release and flopped at the box office. His next film, Gemini Raghava’s Vaidehi (2009), also starred the same lady.

He was injured and burned in a fire while filming Padhinettan Kudi Ellai Arambam. The film was released in December 2011 with little fanfare. Varatti was his latest project in 2011, which he worked on with his brother Prem Rajan.

He competed in the Celebrity Cricket League for the Chennai Rhinos, earning praise for his skills on the pitch.
