For the Peruvian rock group, see Libido (band).

Libido in its common usage means sexual desire, however more technical definitions, such as found in the work of Carl Jung, are more general, referring to libido as the free creative, or psychic, energy an individual has to put toward personal development, or individuation.

Sigmund Freud introduced the term and pointed out that libido is the instinctual energy or force that can come into conflict with the conventions of civilized behavior. It is the need to conform to society and control the libido, contained in what Freud defined as the Id, that leads to tension and disturbance in both society and the individual. This disturbance Freud labelled neurosis.

Libido is generally considered synonymous with such concepts as élan vital and psychophysiological energy ; related concepts from Eastern philosophy include Kundalini and Tantra.

Libido can also be classified as the urge to create life. Naturally for humanity the natural way through which this occurs is through sex. However at a deep subconscious level, the two can be merged as one, given the reason in evolutionary terms for sexual attraction and sex drive. Using this term, the antonym of libido is destrudo.
