The study explored the impact of liquidity management on financial performance of listed deposit money banks in Nigeria. The population of this study comprises all the listed Deposit Money Banks on the Nigeria Stock Exchange (NSE) as at 31 st December, 2020, which constitutes Sixteen (16) Banks. Fourteen (14) Banks were emerged as sample after two (2) were filtered out based on some criteria. Data were collected from the annual reports and accounts of the sample Banks for the period of the study. Collected data were analysed using descriptive statistics, correlation and multiple regression technique. The findings of the study revealed that Liquidity ratio (LR) has positive and significant impact on the financial performance of listed Deposit Money Banks in Nigeria. The finding further shows that cash reserve ratio (CRR) is negative and significantly related to the financial performance of listed Deposit Money Banks in Nigeria. Finally, the finding shows that Loan to debt ratio (LDR) has a positive but insignificant relationship with financial performance of listed Deposit Money Banks in Nigeria. The study therefore, concludes that Liquidity ratio and Loan to deposit ratio have an impact in influencing the financial performance of listed DMB's in Nigeria. It is therefore recommended that the listed DMBs should pay attention on their liquidity by increasing its level through prudent spending, aggressive deposit and debt recovery. Regulatory agencies such as Nigerian Deposit insurance commission (NDIC), Central bank of Nigeria and the Board of directors should mandate the increase in percentage of loans that DMB's give to customers so as to increase their performance.
