Indian poet, novelist, and travel writer known for his verse novel The Golden Gate (1986) and his epic novel A Suitable Boy (1993).

The son of a judge and a businessman, Seth was raised in London and India. He attended exclusive Indian schools and then graduated from Corpus Christi College, Oxford (B.A., 1975). He received a master's degree in economics from Stanford University in 1978 and later studied at Nanking (China) University. In 1987 he returned to India to live with his family in New Delhi.

Although Seth's first volume of poetry, Mappings, was published in 1980, he did not attract critical attention until the publication of his humorous travelogue From Heaven Lake (1983), the story of his journey hitchhiking from Nanking to New Delhi via Tibet. The poetic craft of The Humble Administrator's Garden (1985) foreshadows the polish of The Golden Gate, a novel of the popular culture of California's Silicon Valley, written entirely in metred, rhyming 14-line stanzas and based on Charles Johnston's translation of Aleksandr Pushkin (Pushkin, Aleksandr Sergeyevich)'s Eugene Onegin. In the work Seth successfully harnesses contemporary situations to a demanding 19th-century form; the young professional characters discuss nuclear weapons, Roman Catholic teachings on homosexuality, and the perils of overwork. Seth continued to use controlled poetic form in his 1990 collection All You Who Sleep Tonight, and he also wrote the 10 stories of Beastly Tales from Here and There (1992) in tetrametre couplets. A collection entitled The Poems, 1981–1994 was published in 1995. He turned to prose, however, in A Suitable Boy, which depicts relations between four Indian families. The book's compelling narrative and great length invited critical comparisons to Leo Tolstoy (Tolstoy, Leo), Marcel Proust (Proust, Marcel), James Joyce (Joyce, James), Honoré de Balzac (Balzac, Honoré de), and Charles Dickens (Dickens, Charles). His next novel, An Equal Music (1999), is a love story set in the world of professional musicians.
