The Algebra of Infinite Justice (2001) is a collection of essays written by Booker Prize winner Arundhati Roy.

The book discusses a wide range of issues including political euphoria in India over its successful nuclear bomb tests, the effect of public works projects on the environment, the influence of foreign multinational companies on policy in poorer countries, and the "war on terror".

Mithu C Banerji, in a review in The Observer (2002), stated: Roy's writing reflects her fiction, and meanders between polemic and sentiment.

[10] Mehraan Zaidi of Hindustan times said:Today in this world there are very few people who have the power and skill to change the way you look towards life through their writings.
