Who is a Hindu?

Who is a Hindu? is a book by Koenraad Elst published in 2001 by Voice of India.

In the first part of the book, Elst tries to give a definition to the term "Hindu", although he writes that "there is no simple solution for the complex question, “Who is a Hindu?”" He also compares Hinduism with monotheistic creeds.

The book then discusses whether Hindu reformists, Buddhists, Jains or Sikhs can be considered as Hindus. Other topics in the book include the Caste system and Hindutva.
