This study sought to examine the impact of corporate governance on dividend payout of manufacturing firms listed at the NSE. The objectives of the study were; to determine the impact of board size, board composition, CEO tenure and managerial equity holding on dividend payout of manufacturing firms listed at NSE and finally, to establish the impact of corporate governance on dividend payout of manufacturing firms listed at NSE. The study employed a correlational research design and the population of the study comprised all manufacturing firms which were consistently listed at the Nairobi Securities Exchange from 2008-2014. Correlation and regression analysis were used to test the impact of the independent variables relating to corporate governance practices on the dependent variable (Dividend Payout). Independent one-way ANOVA test and independent t-test (one tailed) were used to determine the level of significance. The study found that board size, board composition, CEO tenure and management equity holding have a weak negative relationship with dividend payout. Further, the study found that board size has a statistical significant impact on dividend payout, while board composition, CEO tenure and managerial equity holding were found to have no statistical significant impact on the dividend payout. The empirical results from the multiple regression analysis indicated that there is a strong positive relationship between corporate governance and dividend payout. However, there was no statistical significant relationship between the two variables. Therefore, this study concludes that corporate governance has no impact on dividend payout of manufacturing firms listed at NSE.
