Barbara Branden (born Barbara Weidman; 14 May 1929 – 11 December 2013) was a Canadian writer, editor and lecturer. She is best known for her close involvement with, and later public break from, novelist-philosopher Ayn Rand. Her career combined writing, public speaking and work that documented the inner history of a prominent intellectual movement.

Born Barbara Weidman, she became a prominent figure in mid-20th-century American intellectual circles through personal and professional ties. She married Nathaniel Branden, a psychologist and leading proponent of Rand’s ideas, and together they played a role in promoting and organizing study groups and lectures on Objectivism. That collaborative period helped shape her public profile.

Barbara Branden wrote and edited on subjects related to the movement she had helped publicize and later to the life of its founder. Her best-known book, The Passion of Ayn Rand, is a biographical account that combines reportage, interviews and personal recollection to portray Rand’s life and relationships. The book drew attention for its detailed narrative and for the controversy it provoked among Rand’s followers.

The end of her friendship with Ayn Rand marked a turning point. In the late 1960s a highly public rupture occurred between Rand and the Brandens that led to their exclusion from Rand’s inner circle. The episode is often cited in histories of the movement as an example of the personal and ideological tensions that affected its development.

In later years Barbara Branden continued to lecture and write about the intellectual history she had witnessed, and she took part in debates over how Rand’s life and ideas should be interpreted. Her work remains a source for scholars and readers interested in biographical detail and the human context behind a widely discussed philosophical movement. She died in 2013, leaving a contested but influential record of that period.
