Background and Aim: Hospital's traditional charter that mostly emphasized productivity has been replaced by a charter that stresses social and environmental issues. On this basis, to achieve success, managers should regard both the inner and the outer environments of hospitals. This study aims at measuring hospitals' social responsibility.

Materials and Methods: The present descriptive-analytic study was carried out through a cross-sectional method in 2010. The study population consisted of hospital managers of the city of Isfahan (n=21). The data collection instrument was a researcher-made questionnaire. The instrument's content validity was determined by the experts' views and its reliability calculated through Cronbach's α was found to be 0.95. The collected data were analyzed using SPSS software (version 16) and the hypotheses were tested by t-test, ANOVA and Eta coefficients. The maximum mean score was 100.

Results: The mean score of hospitals' social responsibility was computed to be 68.6. The mean scores of leadership and inner processes, market place, community policies, environmental policies, and workplace policies were found to be 72.2, 70, 67.8, 67.4 and 66.2, respectively.

Conclusion: The social responsibility of hospitals was assessed as moderate. To improve hospital's social responsibility, it is suggested that more attention be paid to workplace and environmental policie
