This study examined the relationship tenure of audit committee and voluntary disclosure in deposit money banks in Nigeria. Voluntary disclosure was proxied using strategic information disclosure and non-financial information disclosure. Data for this study was collected from the annual reports and accounts of the sampled listed deposit money banks in Nigerian Exchange Group Fact Book. The data covered the period from 2010 to 2021. Analysis for this study was tested using the Ordinary Least Square (OLS) multiple regression model with the aid of the E-View 10. Findings from the study revealed that tenure of audit committee does not have a significant relationship with strategic information disclosure, and tenure of audit committee have a significant relationship with non-financial information disclosure. Therefore, the study concludes that audit committees may need to focus on other attributes, beyond tenure, to enhance strategic disclosures. Based on this conclusion, the study recommends that management of deposit money banks encourage longer tenures for audit committee members. It is important that irrespective of the long tenure there is need for periodic rotation of audit committee members.
