Introduction: Advocacy involves publicly addressing issues of interest, supporting causes or ideas, and using communication and persuasive actions to influence policies, positions, and programs. The literature identifies advocacy as a traditional role of occupational therapists. Objective and Method: This study aims to present reflections and examples of how occupational therapy territorial-community practices can advocate and foster the social participation of individuals and groups whose occupations have been disrupted, based on practical Brazilian experiences. Results and Practice Implications: Territorial-community practices are strategic initiatives focused on developing activities with the target population, incorporating social, historical, economic, political, and cultural dimensions. This approach is grounded in contextual engagement and the local collective dynamics. Our experiences highlight several strategies in this practice, such as actively engaging in collective and social relationships; weaving formal and informal networks; building connections through activities; fostering horizontality and openness in relationships; and addressing social vulnerability in everyday life and public policies. Territorial-community practices move beyond advocacy for individual demands, aiming instead to advocate with, to promote autonomy, participation, access to social rights, and occupational participation in desired activities. Occupational therapists should act as mediators between individuals and collectives, their occupations, and their territories. Conclusion: Occupational therapists are encouraged to develop revolutionary practices to build an effectively transformative occupational therapy. Advocacy and territorial-community practices are the initial steps in search of meaningful changes.
