The purpose of this article was to examine the relationship between profitability and voluntary disclosure practices in the Kenyan banking sector. To measure the extent of disclosure, an un-weighted disclosure index consisting of 40 items was applied. The study employed ordinary least squares technique to analyse the data. On average, voluntary disclosure level of the Kenyan banks was found to be at 62.8%. Results show that profitability, listing status and size of the bank are positively and significantly associated with voluntary disclosure levels. In order to improve the general level of banks disclosure, there is a need for regulatory agencies in Kenya to strengthen compliance to the existing disclosure requirements.
