Public relations as “An Effective Tool for Gender Equality and National Development” have received much attention from authors, researchers, practitioners and the society. Gender equality is disparity in access to opportunity to contest election or appointment into various positions of governance in Nigeria. Gender disparity is created and widened in most developing countries not only by economic circumstance but by the forces of culture. The objective of this study is to investigate public relations as an effective tool for gender equality and national development with focus in South-East, Nigeria and to what extent women have been discriminated in governance. It was observed that these women are discriminated against in governance. Existing data and survey methods were employed in the collection of the data. It was further observed that women were not given equal opportunity to participate in the mainstream of governance and decision-making positions but merely seen as second class citizens. This study therefore, shows the extent of gender bias and discrimination in the country. These findings were exhaustively discussed and recommendations made to minimize the gap.
