John Hospers was an American philosopher and political activist. Hospers was interested in Objectivism, and was once a friend of the philosopher Ayn Rand, though she later broke with him. In 1972, Hospers became the first presidential candidate of the Libertarian Party, and was the only minor party candidate to receive an electoral vote in that year's U.S. presidential election.

Objectivism is a philosophical system named and developed by Russian-American writer and philosopher Ayn Rand. She described it as "the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute".
