Abstract: The devolution that was done in Tanzania in the 1990s brought several challenges, one of them being grand corruption in the local governments. The purpose of this research was to investigate the role of governance in combating corruption in local government authorities in Tanzania using Mbozi district council and focusing on accountability, transparency, and integrity and influence leadership. The sample of sixty one (61) respondents drawn from a target population of 72; comprising of the Council Management Team, Councilors and the Members of the Ward Development Committees from four wards was used. The data gathered were both quantitative and qualitative obtained by using questionnaires and interview guide respectively. The collected data was analyzed both quantitatively and qualitatively. Quantitative data was analyzed using descriptive (mean and percentages) and inferential statistics (Pearson Correlation Coefficient). Thematic analysis was used to analyze the qualitative data. The results revealed that there was a significant correlation between the roles of accountability (0.453) and combating of corruption. The study suggests more improvement in the accountability in Mbozi district council. To achieve this there should be programmes for empowering citizens to demand for more accountability from their local government.
