Abstract The main objective of this research was to investigate the relationship between financial constraints and audit fees. The sample of the study included 93 nonfinancial listed companies on the Egyptian Stock Exchange during the period from 2018 to 2022. The total number of observations was 465 observations. The research results concluded a positive significant relationship between financial constraints and audit fees. The researcher recommends the need to find scientific methods to be used to determine audit fees that are consistent with the effort expended when conducting the audit process, instead of making the process of determining audit fees a matter of judgment that varies from one company to another. It is necessary for professional and regulatory bodies to issue financing programs and establish special funds to assist financially constrained companies, whether with financial assistance or by providing guidance to emerge from this crisis, to limit these companies' resort to means that threaten the efficiency of the capital market. In addition, researchers to be aware of the importance of conducting further accounting studies and research on financial constraints and its effects on the Egyptian business environment.
