In general, the variables used in this study consisted of financial inclusion variables and non- financial inclusion variables. Proxies of financial inclusion variables consist of office networks, ATM networks and savings customers. Non- financial inclusion variable proxies consist of third deposit funds, interest rates, profitability, yield equivalent and size of sharia banking. This research is a type of quantitative research using the Vector Error Correction Model (VECM) using the Eviews analysis tool. Based on the results of data analysis, the proxy for financial inclusion variables that affect Islamic banking deposits is the office network (KTR) and the ATM network (ATM), while the proxy variable that has no effect is the deposit customer (NSB). Non- financial inclusion variables that affect Islamic banking deposits are the equivalent yield (ER) and the size of Islamic banking (SZE), while variables that do not affect Islamic banking deposits are the benchmark interest rate (BIR) and profitability (PRO).Keywords: Financial Inclusion, Third Deposit Funds, Islamic Banking
