The 52nd Annual ONS Congress will take place from April 14–18, 2027, at the Walter E. Washington Convention Center in Washington, DC, USA.

Organized by the Oncology Nursing Society (ONS), the congress will bring together oncology nurses and other healthcare professionals for education, professional development, research exchange, and discussion of advances in cancer care.

The 2027 congress will feature education across different stages of oncology nursing practice, with sessions focused on symptom management, cancer care delivery, evidence-based practice, research, access, quality and value in cancer care, and professional development. The programme will include expert-led sessions, oral abstract presentations, poster presentations, and industry-supported events. Attendees can also earn more than 20 NCPD contact hours.

The congress provides an opportunity for oncology professionals to share research and quality-improvement work while connecting with colleagues from across the cancer-care community. Accepted abstracts will be published in the Oncology Nursing Forum in spring 2027.
