Community art, also known as social art, community-engaged art, community-based art, and, rarely, dialogical art, is the practice of art based in—and generated in—a community setting. It is closely related to social practice and social turn. Works in this form can be of any media and are characterized by interaction or dialogue with the community. Professional artists may collaborate with communities which may not normally engage in the arts. The term was defined in the late 1960s as the practice grew in the United States, Canada, the Netherlands, the United Kingdom, Ireland, and Australia. In Scandinavia, the term "community art" more often refers to contemporary art projects.

Community art is a community-oriented, grassroots approach, often useful in economically depressed areas. When local community members come together to express concerns or issues through this artistic practice, professional artists or actors may be involved. This artistic practice can act as a catalyst to trigger events or changes within a community or at a national or international level. A recent example is that of the Brooklyn Immersionists who created dynamic events in the streets, rooftops and abandoned warehouses along Brooklyn’s industrial waterfront in the 1990s. The emergence of creative networks helped to bring local businesses back to the area and lowered the rate of attrition for the disadvantaged in that economically struggling district. The attrition rates reversed when the City of New York privileged corporate developers in the new millennium.

In English-speaking countries, community art is often seen as the work of community arts centers, where visual arts (fine art, video, new media art), music, and theater are common media. Many arts organizations in the United Kingdom do community-based work, which typically involves developing participation by non-professional members of local communities.

The term "community art" may also apply to public art efforts when, in addition to the collaborative community artistic process, the resulting product is intended as public art and installed in public space. Popular community art approaches to public art can include environmental sustainability themes associated with urban revitalization projects.

Models of community-engaged arts can vary with three forms of collaborative practices emerging from among the sets of common practices. In the artist-driven model, artists are seen as the catalysts for social change through the social commentary addressed in their works. A muralist whose work elicits and sustains political dialogue would be a practitioner of this model. In the second model, artists engage with community groups to facilitate specialized forms of art creation, often with the goal of presenting the work in a public forum to promote awareness and to further discourse within a larger community. In the process-driven or dialogic model, artists may engage with a group to facilitate an artistic process that addresses particular concerns specific to the group. The use of an artistic process (such as dance or social circus) for problem-solving, therapeutic, group-empowerment or strategic planning purposes may result in artistic works that are not intended for public presentation. In the second and third models, the individuals who collaborate on the artistic creation may not define themselves as artists but are considered practitioners of an art-making process that produces social change.

Due to its roots in social justice and collaborative, community-based nature, art for social change may be considered a form of cultural democracy. Often, the processes (or the works produced by these processes) intend to create or promote spaces for participatory public dialogue.

In Canada, the field of community-engaged arts has recently seen broader use of art for social change practices by non-arts change organizations. The resultant partnerships have enabled these collaborative communities to address systemic issues in health, education, as well as empowerment for indigenous, immigrant, LGBT and youth communities. A similar social innovation trend has appeared where business development associations have engaged with artists/artistic organizations to co-produce cultural festivals or events that address social concerns.

As the field diversifies and practices are adopted by various organizations from multiple disciplines, ethics and safety have become a concern to practitioners. As a result, opportunities for cross-disciplinary training in art for social change practices have grown within the related field of arts education.
