The ability to communicate effectively with citizens is a fundamental function of good governance. This study investigates effective communication as a tool for good governance in Nigeria. The survey research method was adopted and questionnaire was used as data collection instrument. Using the convenient sampling technique, a sample size of 500 respondents was selected from the population of 485,063. Findings showed that the flow of information between government and citizens is not adequate and the extent to which the media have discharged their duties towards ensuring adequate flow of information between the government and the citizens is negligible. Accordingly, the paper recommends that there is need for a two-way approach of information flow between the government and the citizens; and that journalists/media workers should demonstrate greater commitment to fairness, balance and social responsibility in their coverage and dissemination of information.
