约翰·布罗德斯·华生（英语：John B. Watson，1878年1月9日－1958年9月25日）是一位美国心理学家，通过动物行为研究而创立了心理学行为主义学派，强调心理学是以客观的态度去研究外在可观察的行为。华生认为，人的所有行为性格都是后天习得，他以宣称能将任意一打健全的婴儿用适当的行为技术创造成想要的任何类型的人而着称。他还进行了有争议的“小艾伯特实验”。后来，他继续发表儿童教育方面的心理学普及读物，并成为广受欢迎的广告设计者。

John Broadus Watson (January 9, 1878 – September 25, 1958) was an American psychologist who established the psychological school of behaviorism. Watson promoted a change in psychology through his address Psychology as the Behaviorist Views it, which was given at Columbia University in 1913. Through his behaviorist approach, Watson conducted research on animal behavior, child rearing, and advertising. In addition, he conducted the controversial "Little Albert" experiment. He was also editor of Psychological Review from 1910 to 1915. A Review of General Psychology survey, published in 2002, ranked Watson as the 17th most cited psychologist of the 20th century.
