This study explores the dual challenges of ageism and professional recognition faced by senior nurses in healthcare settings. Utilizing a phenomenological approach, we conducted semi-structured interviews with 20 registered nurses aged 50 and older in Abha City, Saudi Arabia. The analysis revealed four key themes: experiences of ageism, its impact on professional roles, discrimination and stigmatization, and the need for organizational support. Findings indicate that age-related biases lead to significant professional marginalization, reduced job satisfaction, and emotional distress among senior nurses. The study highlights the critical need for comprehensive policies, organizational support, and cultural changes to address ageism and recognize the valuable contributions of senior nurses. Promoting an inclusive work environment and equitable professional development opportunities can enhance the overall quality of care and job satisfaction for older nurses.
