Aesthetics (also esthetics in American English), is a branch of philosophy that deals with the nature of beauty and taste, as well as the philosophy of art (its own area of philosophy that comes out of aesthetics). It examines aesthetic values, often expressed through judgments of taste. Aesthetics covers both natural and artificial sources of experiences and how we form a judgment about those sources. It considers what happens in our minds when we engage with objects or environments such as viewing visual art, listening to music, reading poetry, experiencing a play, watching a fashion show, movie, sports or even exploring various aspects of nature. The philosophy of art specifically studies how artists imagine, create, and perform works of art, as well as how people use, enjoy, and criticize art. Aesthetics considers why people like some works of art and not others, as well as how art can affect moods or even our beliefs.

Aesthetics in this central sense has been said to start with the series of articles on "The Pleasures of the Imagination", which the journalist Joseph Addison wrote in the early issues of the magazine The Spectator in 1712. The term aesthetics was appropriated and coined with new meaning by the German philosopher Alexander Baumgarten in his dissertation Meditationes philosophicae de nonnullis ad poema pertinentibus () in 1735; Baumgarten chose "aesthetics" because he wished to emphasize the experience of art as a means of knowing. Baumgarten's definition of aesthetics in the fragment Aesthetica (1750) is occasionally considered the first definition of modern aesthetics. The term was introduced into the English language by Thomas Carlyle in his Life of Friedrich Schiller (1825).
