The deutsche Occupational Science (dOS) is a German organization dedicated to developing and promoting occupational science in Germany. It approaches occupation as an interdisciplinary field of study, examining the relationship between human occupation, health, wellbeing, and the social, cultural, temporal, and environmental contexts in which people live.

dOS provides a German context for the discussion and development of occupational science while connecting the field with broader academic and professional conversations. Its work contributes to strengthening understanding of occupation as an important area of knowledge for occupational therapy and other disciplines.
