The Billionaire Raj: A Journey Through India's New Gilded Age is a 2018 non-fiction book written by British author James Crabtree.

In the Literary Review, Oliver Balch calls the book "thoroughly entertaining" and writes that the economic content "neither bores nor overbears", but criticises the "familiarity of some of its examples".

[1] A Publishers Weekly review lauds the book as "an invaluable commentary on Indian democracy", and praises Crabtree for "[bringing] a reporter's precision and flair to his story".

[5] Writing in the Financial Times, Meghnad Desai describes the book as “the most comprehensive and eminently readable tour of economic India.”[6] Jonathan Knee of The New York Times laments that the book "does not fully profile the diverse community of Indian billionaires" and that "the lines between the many forms of corruption described are far from clear", though Knee praises that The Billionaire Raj "is chock-full of profoundly revealing vignettes".

[8] comments on the absence of IT entrepreneurs, but believes there is "no comparable account of India's gilded age", complimenting the book as "a reporting gem" which "deserves to be widely read".
