Objectivism: The Philosophy of Ayn Rand is a 1991 book by philosopher Leonard Peikoff, in which the author discusses the ideas of his mentor, Ayn Rand.
 Peikoff describes it as "the first comprehensive statement" of Rand's philosophy, Objectivism.
 The book is based on a series of lecture courses that Peikoff first gave in 1976 and that Rand publicly endorsed.
 Peikoff states that only Rand was qualified to write the definitive statement of her philosophic system, and that the book should be seen as an interpretation "by her best student and chosen heir."
 The book is volume six of the "Ayn Rand Library" series edited by Peikoff.

The Objectivist movement seeks to study and advance Objectivism, the philosophy of Ayn Rand.
 It was founded by novelist, screenwriter, and philosopher Ayn Rand.
 The movement began informally in the 1950s and consisted of students who were brought together by their mutual interest in Rand's novel, "The Fountainhead".
 The group, ironically named "the Collective" due to their actual advocacy of individualism, in part consisted of Nathaniel Branden, Barbara Branden, Alan Greenspan, and Leonard Peikoff.
 Nathaniel Branden, a young Canadian student who had been greatly inspired by Rand's work, became a close confidant and encouraged Rand to expand her philosophy into a formal movement.
 From this informal beginning in Rand's living room, the movement expanded into a collection of think tanks, academic organizations, magazines, and journals.
