This study empirically examined the impact of working capital management (Measured by: the number of days accounts receivable are outstanding-DAR, the number of days inventory are held-DINV, and the cash conversion cycle-CCC), on profitability (measured by return on assets-ROA) of Nigerian Cement Industry for a period of eight (8) years (2002-2009). Data from a sample of four (4) out of the five (5) cement companies quoted on the Nigerian Stock Exchange (NSE) were analysed using descriptive statistics and multiple regression analysis. The study found an insignificant negative relationship between the profitability (measured by ROA) of cement companies quoted on the NSE and the number of days accounts receivable are outstanding (DAR). The study also found a significant negative relationship between the profitability of these cement companies and the number of days inventory are held (DINV). The study finally revealed a significant positive relationship between the profitability and the cash conversion cycle (CCC). The study concludes that, the profitability of cement companies quoted on the NSE during the study period is influenced by DINV and CCC. The study therefore recommends that managers of these cement companies should manage their working capital in more efficient ways by reducing the number of days inventory are held to an optimal level in order to enhance their profitability as well as create value for their shareholders. Managers of Nigerian cement companies should also improve on their cash flows, through the reduction of their cash conversion cycle
