It is thought that it is important to consider social capital in terms of business organizations that play an important role in the economic system. In this study, social capital, which is a multidisciplinary concept, is discussed in terms of business organizations, and conceptual information is presented. The core thesis of social capital is that "relationships are important" and social networks are a valuable asset". Since it is very difficult to imitate and transfer the social capital that is formed through the relations between individuals, groups, and organizations, it can be said that it will give organizations a competitive advantage. In addition to the skills needed in business life, social networks and relationships are also important. As a result of the literature research, it is seen that social capital increases job satisfaction, organizational commitment, motivation, and job engagement. However, social capital has been determined to have benefits for individuals, societies, and countries, such as reducing the business concerns of young people, providing advantages for women entrepreneurs, preventing the spread of the virus during the COVID-19 period, increasing life satisfaction and quality of life, having a positive impact on the health status of individuals, and having positive effects on the economic development of countries. The benefits of social capital in terms of individuals, organizations, and countries reveal the importance of this concept. Increasing the studies on this subject can contribute to the literature and practitioners' knowledge, especially since the benefits it provides organizations give them a competitive advantage.
