Eurekha! is a biography of the actress Rekha by the columnist and author Mohan Deep. The book details her Bollywood acting career and her short-term marriage with the industrialist Mukesh Aggarwal. It was published on 17 December 1999 by Shivani Publications and later reprinted in a number of Indian languages, including a serialisation in the magazine Anandalok. It received negative reviews from critics, who panned Deep's writing and the book's contents. Rekha herself was critical of the book due to its misinformation.
