Portnoy's Complaint is a 1969 American novel by Philip Roth. Its success turned Roth into a major celebrity, sparking a storm of controversy over its explicit and candid treatment of sexuality, including detailed depictions of masturbation using various props including a piece of liver. The novel tells the humorous monologue of "a lust-ridden, mother-addicted young Jewish bachelor," who confesses to his psychoanalyst in "intimate, shameful detail, and coarse, abusive language."

Philip Milton Roth was an American novelist and short-story writer. Roth's fiction—often set in his birthplace of Newark, New Jersey—is known for its intensely autobiographical character, for philosophically and formally blurring the distinction between reality and fiction, for its "sensual, ingenious style" and for its provocative explorations of American identity. He first gained attention with the 1959 short story collection Goodbye, Columbus, which won the U.S. National Book Award for Fiction. Ten years later, he published the bestseller Portnoy's Complaint. Nathan Zuckerman, Roth's literary alter ego, narrates several of his books. A fictionalized Philip Roth narrates some of his others, such as the alternate history The Plot Against America.
