This study examines the relationship between monitoring, firm characteristics and dividend policy of listed conglomerate firms in Nigeria for the period of 2010 to 2019. The study used panel data extracted from the Annual Reports and Accounts of all the six (6) listed Conglomerate firms in the Nigerian Stock Exchange as at 31st December, 2019. The study adopted Correlational research design and Generalized Least Squares (GLS) regression technique for data analysis. The study found that profitability and firm size have significant impact on dividend payout ratio, while institutional ownership also has significant effect on dividend payout ratio. However, leverage was found to be statistically insignificant with dividend payout ratio. What left to be done therefore, is for the management of listed conglomerate firms in Nigeria to ensure a stable balance between their previous, current and future profits potentials and be conscious of their investment, long-term solvency and corporate size whenever it comes to profit decision-making as they have been empirically found to have a significant impact on dividend policy of listed conglomerate firms in Nigeria.
