George Stuart Fullerton (1859–1925) was an American philosopher and psychologist. Fullerton was born at Fatehgarh, India, the son of the Rev. Robert Stuart Fullerton. He came to this country as a youth.
He graduated in 1879 from the University of Pennsylvania and in 1884 from Yale Divinity School; and returned to Pennsylvania to be an instructor, adjunct professor, and dean of the department of philosophy, dean of the college, and vice provost of the university. In 1904 he was appointed professor of philosophy at Columbia University, and served as head of the department.
He was the host of the first annual meeting of the American Psychological Association in 1892 at the University of Pennsylvania, and the APA's fifth president, in 1896.
