This paper aims to disclose the mediating effect of self-worth and depression on the relationship between subjective age and subjective well-being of the elderly. For this purpose, 238 questionnaires were issued to elderly in Shaanxi, China. 219 (92.02%) of valid questionnaires were returned. During the survey, the respondents evaluated each item on the questionnaire against the age decade scale (ADS), geriatric depression scale (GDS-11), geriatric self-worth scale (GSWS) and Memorial University of Newfoundland Scale of Happiness (MUNSH). The main conclusions are as follows: Feel age, look age, behavior age and interest age were all lower than the actual age; The old people with a high level of education and a high involvement in leisure activities tend to have a young subjective age; Subjective age had a significant effect on subjective well-being, self-worth and depression, while self-worth and depression mediated the relationship between subjective age and subjective well-being. Therefore, the subjective well-being among the elderly can be promoted by reducing subjective age and enhancing self-worth. This research provides new insights into the research on subjective well-being of elderly
