Abstract: Background:Ethics, often known as moral philosophy, is a branch of philosophy that examines moral questions, such as the concepts of good and evil, right and wrong, virtue, and justice. Ethics consists of two things. First, when we talk about ethics, we're talking about firmly established standards of what is morally right and bad. These laws typically refer to rights, duties, and advantages for society, justice, or particular qualities. A typical characteristic of an ethical dilemma is the seeming conflict between two moral obligations, whereby abiding by one would imply violating the other. Staff nurses make moral decisions every day. The ethical rights of their patients must be respected in these circumstances, and nurses must know how to address them without compromising their own moral principles.Materials and methods: A descriptive study was conducted among 112 staff nurses. Subject was selected using purposive sampling techniques. The information was collected using a demographic Proforma and a self - administered questionnaire. The overall knowledge among ethical legal issues was graded as very good, good, average, poor.Results:The highest percentages (62.5%) of the respondents were in the age of 20-25 years, most (87.5%) of the samples were females. 27. 7% samples working in surgical departments and majority (66.1%) had 0-2 years work experience. Majority (54.5%) of the staff nurses had good knowledge in ethical – legal issues. The mean knowledge score was 15 ± 3.54 Mean percentages was 65.  Significant association found between knowledge and gender (p= 0.04) and year of experience (p= 0.02).Conclusion: The ethical behavior of healthcare workers has become a subject of significant public concern. This study proved that most of the staff nurses have good knowledge regarding ethical legal issues
