This paper examined audit committee characteristics on audit quality in Nigeria, for 10 years spanning from 2009-2018. Specifically, this study assessed the effect of audit committee size on audit quality in the oil and gas sector and examined the effect of audit committee meetings on audit quality in the oil and gas sector. The study adopted an expo-facto research design and the population covered all the 12 listed Oil and Gas sectors; out of which, 10 firms were selected through a random sampling technique. The study used secondary data, sourced from the published financial reports of the sampled firms covering the period of 2009-2018. Through logistic regression, it was discovered that audit committee size exerted a positive significant effect on audit quality of firms in the oil and gas sector in Nigeria and that audit committee meeting exerts a positive but insignificant effect on audit quality of firms in the oil and gas sector in Nigeria. It was concluded that audit committee has a statistically significant effect on audit quality in Nigeria. Thus, it was recommended that emphasis and focus should be placed on the size of the audit committee to improve audit quality and that modalities surrounding the meetings of the committee members should be revisited. Also, adequate supervision and monitoring should be ensured in every meeting of the committee members.
