Faith of My Fathers is a 1999 bestselling non-fiction book by United States Senator John McCain with Mark Salter.

[1] After that book found critical praise, Timberg's literary agent tried to persuade McCain to write his own memoir on the subject; he was reluctant until she suggested he fold in the stories of his father and grandfather as well.

[2] The book's themes were heavily influenced by McCain's literary tastes, such as Ernest Hemingway's For Whom the Bell Tolls, and its tone by Salter's gloomy view of human nature.

[2] The book was a commercial success, spending 24 weeks on the New York Times Best Seller list between September 1999 and March 2000, with a peak position of number two,[3] and selling over 500,000 copies.

McCain also wrote a sequel memoir, 2002's Worth the Fighting For, that covered his life after returning from Vietnam and as a politician.
