AbstractSport is one of the most international industries in the world and relies on entrepreneurship to ensure its competitiveness. Due to the COVID‐19 pandemic, the sport industry had to rapidly change and adjust to international border closures and reduced physical contact activity. Many people involved in the sport industry are located outside of their home country and form part of the diaspora network of sport professionals. The diaspora is highly active in the sport industry in terms of disseminating ideas and utilizing their social networks for international entrepreneurial purposes. The aim of this article is to examine the impact of the diaspora on international sport entrepreneurship thereby contributing a novel approach to the international entrepreneurship, sport entrepreneurship and diaspora entrepreneurship fields in a way that has not been contemplated before. A qualitative research methodology is employed to interview sport entrepreneurs about their diaspora and international entrepreneurship activities. This enables a holistic understanding about the role of international public/private partnerships for the success of innovative and futuristic entrepreneurial sport activity. A theoretical framework based on the interview data was developed that incorporated a three‐level process of international drivers, diaspora types and sport entrepreneurship outcomes. A number of research propositions were then derived from the data that highlight how the sport industry is highly international and relies on internationalization to foster new business activity. Policy and managerial implications about the role of diaspora for international sport entrepreneurship are highlighted together with future research suggestions.
