Someone who choses nursing as a discipline should be aware that he/she may interface with ethical issues every moment. Ethical climate determines how much do the nurses must act according to ethical standards. So the main of this study is the hospital's ethical climate and nurse's desired ethical climate in Ali-ebn-Abitaleb and Khatam-al- Anbia hospitala of Zahedan. This was a cross sectional study and 250 nurses were randomly selected. Data were collected through a questionnaire which included 2 parts. First part included demographic data and the second part included two questionnaires about nurse's perception about ethical climate and their desired ethical climate. Finally data were analyzed by SPSS v.19 through descriptive statistics, T-Test and ANOVA. Mean age of respondents was 30.18±3.93. 113 nurses were from Khatam-al-Anbia hospital and 138 were from Ali-ebn-Abitaleb. There was significant differences between mean score of nurses perception about ethical climate and their desired ethical climate (p=0.02). The ethical climate was proper in nurses viewpoint (mean score= 94.78±15.35). The ethical climate was a satisfactory ethical climate in this study. But it was different with nurse's desired ethical climate. So then we suggest the authorities to keep this ethical climate and plan to make it better.
