Gerotranscendence is a culture-dependent concept involving growth and excellence in old age. While it has been studied in various cultural contexts, little is known about Iranian older adults. This study aims to uncover novel aspects of Iranian older adults’ psychological and transcendental capacities using their lived experiences. A qualitative research approach with a descriptive phenomenological design was employed. Semi-structured and in-depth interviews were conducted with eight older adults (aged 65+) in Tehran, Iran, using a purposive sampling technique. Gerotranscendence among Iranian older adults encompasses four dimensions: self-transcendence, communicative transcendence, worldview transcendence, and harmony of experiences. While sharing commonalities with existing theories, these dimensions exhibit differences that underscore the importance of a culturally sensitive understanding. This study offers unique insights into the development of gerotranscendence in Iranian older adults, highlighting the cultural context of this multifaceted concept. By considering these dimensions in diverse cultural settings, future research can inform tailored interventions and support systems for older adults.
