Teacher wellbeing is important, not least for the role teachers play in supporting students' social, emotional, physical and academic wellbeing. Effective teachers need to remain both physically and mentally healthy. This paper examines how teacher wellbeing is conceptualised through research to identify the influential ecological influences that support and sustain teachers. Through a scoping review methodology, this examination starts with a conceptualisation of teacher wellbeing, and is then organised into three interrelated themes. This thematic approach provides a basis to examine, first, the influential individual factors shaping teachers' wellbeing; second, the relational factors that characterise teachers' work; and, third, the contemporary contextual factors associated with enhancing or eroding teacher wellbeing. These themes highlight that many approaches to enhancing teachers' wellbeing are often short-term "band-aid fixes," and the authors argue that attention must be given to longer-term "bridge-building" strategies that place teacher wellbeing at the heart of teaching.
