The study examined socioeconomic influence of Covid-19 on the informal sector in Nigeria, drawing insight from Enugu State. Data obtained from 340 informal business operators in rural, urban/semi-urban areas, descriptive statistics, and binary logistic model were used to analyse socioeconomic characteristics and socioeconomic influence of Covid-19 on the informal sectors.  Findings suggest that majority (83%) of the informal business operators were affected adversely by COVID-19. Sampled informal sector businesses were male-dominated, and rural-dominated by location. Logistic regression revealed some significant socioeconomic influences of COVID-19 on the informal sector businesses. Such socioeconomic characteristics include age, sex, location, occupation, cost of transportation, cost of labour, and palliative receipt during the Covid-19 pandemic. Government should integrate the informal sector into the Nigerian economic development and sustainable plan in the post-Covid-19 period to ensure that the informal sector operates in a sustainable manner, and increased palliatives to enhance informal sector quick recovery is required.
