Academic art, academicism, or academism, is a style of painting and sculpture produced under the influence of European academies of art. This method extended its influence throughout the Western world over several centuries, from its origins in Italy in the mid-16th century, until its dissipation in the early 20th century. It reached its apogee in the 19th century, after the end of the Napoleonic Wars in 1815. In this period, the standards of the French Académie des Beaux-Arts were very influential, combining elements of Neoclassicism and Romanticism, with Jean-Auguste-Dominique Ingres a key figure in the formation of the style in painting. The success of the French model led to the founding of countless other art academies in several countries. Later painters who tried to continue the synthesis included William-Adolphe Bouguereau, Thomas Couture, and Hans Makart among many others. In sculpture, academic art is characterized by a tendency towards monumentality, as in the works of Auguste Bartholdi and Daniel Chester French.

The academies were established to replace medieval artists' guilds and aimed to systematize the teaching of art. They emphasized the emulation of established masters and the classical tradition, downplaying the importance of individual creativity, valuing instead collective, aesthetic and ethical concepts. By helping raise the professional status of artists, the academies distanced them from artisans and brought them closer to intellectuals. They also played a crucial role in organizing the art world, controlling cultural ideology, taste, criticism, the art market, as well as the exhibition and dissemination of art. They wielded significant influence due to their association with state power, often acting as conduits for the dissemination of artistic, political, and social ideals, by deciding what was considered "official art". As a result, they faced criticism and controversy from artists and others on the margins of these academic circles, and their restrictive and universalist regulations are sometimes considered a reflection of absolutism.

Overall, academicism has had a significant impact on the development of art education and artistic styles. Its artists rarely showed interest in depicting the everyday or profane. Thus, academic art is predominantly idealistic rather than realistic, aiming to create highly polished works through the mastery of color and form. Although smaller works such as portraits, landscapes and still-lifes were also produced, the movement and the contemporary public and critics most valued large history paintings showing moments from narratives that were very often taken from ancient or exotic areas of history and mythology, though less often the traditional religious narratives. Orientalist art was a major branch, with many specialist painters, as were scenes from classical antiquity and the Middle Ages. Academic art is also closely related to Beaux-Arts architecture, as well as classical music and dance, which developed simultaneously and hold to a similar classicizing ideal.

Although production of academic art continued into the 20th century, the style had become vacuous, and was strongly rejected by the artists of set of new art movements, of which Realism and Impressionism were some of the first. In this context, the style is often called "eclecticism", "art pompier" (pejoratively), and sometimes linked with "historicism" and "syncretism". By World War I, it had fallen from favor almost completely with critics and buyers, before regaining some appreciation since the end of the 20th century.

The first academy of art was founded in Florence by Cosimo I de' Medici, on 13 January 1563, under the influence of the architect Giorgio Vasari, who called it the Accademia e Compagnia delle Arti del Disegno (Academy and Company for the Arts of Drawing) as it was divided in two different operative branches. While the company was a kind of corporation that every working artist in Tuscany could join, the academy comprised only the most eminent artists of Cosimo's court, and had the task of overseeing all Florentine artistic activities, including teaching, and safeguarding local cultural traditions. Among the founding members were Michelangelo, Bartolomeo Ammannati, Agnolo Bronzino and Francesco da Sangallo. In this institution, students learned the "arti del disegno" (a term coined by Vasari) and heard lectures on anatomy and geometry. The Accademia's fame spread quickly, to the point that, within just five months of its founding, important Venetian artists such as Titian, Salviati, Tintoretto and Palladio applied for admission, and in 1567, King Philip II of Spain consulted it about plans for El Escorial.

Another academy, the Accademia de i Pittori e Scultori di Roma (Academy of Painters and Sculptors of Rome), better known as the Accademia di San Luca (named after the patron saint of painters, St. Luke), was founded about a decade later in Rome. It served an educational function and was more concerned with art theory than the Florentine one, attaching great importance to attending theoretical lectures, debates and drawing classes. Twelve academics were immediately appointed as teachers, establishing a series of disciplinary measures for studies and instituting a system of awards for the most capable students.

In 1582, the painter and art instructor Annibale Carracci opened his very influential Accademia dei Desiderosi (Academy of the Desirous) in Bologna without official support; in some ways, this was more like a traditional artist's studio, but that he felt the need to label it as an "academy" demonstrates the attraction of the idea at the time.

The emergence of art academies in the 16th century was due to the need to respond to new social demands. Several states, which were moving towards absolutism, realized that it was necessary to create an art that specifically identified them and served as a symbol of civic unity, and was also capable of symbolically consolidating the status of their rulers. In this process, the Catholic Church, then the greatest political force and social unifier in Europe, began to lose some of its influence as a result of the greater secularization of societies. Sacred art, by far the largest field of artistic expression throughout the Middle Ages, came to coexist with an expanding profane art, derived from classical sources, which had been experiencing a slow revival since the 12th century, and which, by the time of the Renaissance, had been established as the most prestigious cultural reference and model of quality.
