Abstract: Background: Organizational corruption hinders growth, innovation, trust, and transparency which in turn affects nurses' voice. Purpose: The purpose of this study is to assess organizational corruption and its relation to organizational transparency and nurses' voice. Design: Descriptive correlational design was utilized. Setting: The study was conducted in all inpatient units of Benha University Hospital. Sample: A simple random sample of 295 nurses out of 1117 working in the above-mentioned setting was selected and met the criteria for inclusion. Instruments: Three instruments were used; Organizational Corruption Questionnaire, Organizational Transparency Questionnaire, and Employee Voice Behavior Scale (EVBS). Results: Showed that about three-quarters (74.9%) and more than two-thirds (69.5%) of nurses had a high level of perception regarding organizational corruption, and transparency respectively. In addition, less than half (44.5%) of nurses had a moderate promotive and prohibitive voice level. Conclusion: The study concluded that there was a highly statistically significant positive correlation between nurses' perception of organizational corruption, and organizational transparency as well as nurses' voices. Recommendations: The study recommended training nurses on anti-corruption strategies for organizational respect and transparency. Also, giving nurses the chance to speak up (voice) will make them feel more responsible and promote a healthy work environment.
