Seeni Viswanathan

Seeni Viswanathan (, born 22 November 1934) is an Indian Tamil researcher, writer, and editor, primarily known for compiling and publishing the complete works of the renowned Tamil poet and freedom fighter, Subramania Bharati. His extensive research spanning over six decades was published as a comprehensive multi-volume chronological compilation of Bharati's writings. For his contributions, he was awarded the Padma Shri, India's fourth-highest civilian honour, in 2025.

Early life Viswanathan was born on 22 November 1934 in Paramathi Velur, Namakkal district, Tamil Nadu, to P.V. Srinivasan and Kamalambal. He sought out early editions of Bharati's works and copies of journals to which Bharati contributed, such as Swadesamitran, Chakravarthini, and India.

A significant aspect of his research methodology was ensuring textual and factual accuracy, often providing footnotes on textual variations found in different editions. The volumes include commentaries, annotations, background information, documents, and philosophical analysis to provide context for Bharati's writings.
