The Fountainhead is a 1943 novel by Russian-American author Ayn Rand, her first major literary success. The novel's protagonist, Howard Roark, is an intransigent young architect who battles against conventional standards and refuses to compromise with an architectural establishment unwilling to accept innovation. Roark embodies what Rand believed to be the ideal man, and his struggle reflects Rand's belief that individualism is superior to collectivism.

The Fountainhead is a play written in 2014 by Belgian theatre director Ivo van Hove. It is an adaptation of its 1943 novel by American author Ayn Rand. The story focuses on Howard Roark, an individualistic architect who designs modernist buildings and refuses to compromise with an architectural establishment unwilling to accept innovation. The production, running more than four hours, uses video projections to show close-ups of the actors and Roark's drawings, as well as backgrounds of the New York skyline.
