As public facilities and places of worship for the Muslim community, mosques often receive funds from various sources. However, unfortunately, the financial management of mosques in Indonesia is still not optimal. This research was carried out to look at the financial management of mosques. This research was carried out using a qualitative approach. The data used in this study came from various research results and previous studies that discussed financial management carried out in mosques. This study found that the mosque’s function can be optimized to empower the community in social, economic and cultural factors. Unfortunately, the mosque’s cash management by mosque institutions is still not optimal, where only the operational needs of the mosque are repaired, but the need for empowerment of the people is abandoned. Therefore, mosque cash needs to be divided into two, namely productive funds and consumptive funds. This is done so that the mosque’s money can help improve the people’s economy.
