This paper assessed the impact of diaspora remittances on the growth of the Nigerian economy from 1986 to 2019. The paper utilizes the Autoregressive Distributed Lag (ARDL) model by using variables of gross national product, diaspora remittance inflows, labor force, financial development, and trade openness. Results of the study have shown that diaspora remittances have a positive and significant impact on economic growth in Nigeria in the short run and long-run, however, its impact on growth was quite low for both periods. To improve the contributions of diaspora remittance, remittances should go beyond just transfer payments and social security to help family members and serve as investments to spur economic growth. Also, increasing labor force participation through job creation, improving working conditions to enhance productivity, and creating favorable financial environment to invest these funds is advocated. Additionally, international trade should be strengthened by shifting production from primary products such as crude oil and agricultural produce to secondary products such as refined petroleum and industrial products by revamping the industrial sector.
