Individualism is the moral stance, political philosophy, ideology and social outlook that emphasizes the intrinsic worth of the individual. Individualists promote the realisation of one's goals and desires, valuing independence and self-reliance, and advocating that the interests of the individual should gain precedence over the state or a social group, while opposing external interference upon one's own interests by society or institutions such as the government. Individualism is often defined in contrast to totalitarianism, collectivism and more corporate social forms.

Individualism makes the individual its focus and so starts "with the fundamental premise that the human individual is of primary importance in the struggle for liberation". Anarchism, existentialism, liberalism and libertarianism are examples of movements that take the human individual as a central unit of analysis.

Individualism has been used as a term denoting "[t]he quality of being an individual; individuality", related to possessing "[a]n individual characteristic; a quirk". Individualism is also associated with artistic and bohemian interests and lifestyles where there is a tendency towards self-creation and experimentation as opposed to tradition or popular mass opinions and behaviors such as with humanist philosophical positions and ethics.
