This article explores the ubiquitous uses of the term "well-being" in social work codes, values, and literature. It reviews international concepts of well-being as well as those within social work to consider a deeper exploration of the meanings of well-being. Dimensions of well-being that resonate with social work values include eliminating poverty; promoting social inclusion and eliminating oppression; eliminating all forms of violence in society; increasing investments in health, education, and social supports; and the protection and restoration of environmental resources and the biosphere. Frameworks for incorporating concepts of well-being in social work practice, research, and teaching are proposed. (Contains 1 table and 1 figure.)
