Benjamin McLane Spock (May 2, 1903 – March 15, 1998) was an American pediatrician. Spock was the first pediatrician to study psychoanalysis to try to understand children's needs and family dynamics. His ideas about childcare influenced several generations of parents to be more flexible and affectionate with their children, and to treat them as individuals.

In 1946, Spock published his book The Common Sense Book of Baby and Child Care, which became a bestseller. Its message to mothers is that "you know more than you think you do." By 1998 it had sold more than 50 million copies, and had been translated into 42 languages.
