Science Parks convey the idea that technological innovation originates in scientific research. A triple helix configuration provides all the necessary conditions for science parks to achieve their goals. This paper aims to investigate the existing interactions of science parks with triple helix actors related to the development of talent attraction activities. Talent is a necessary resource to meet the growing demands for innovation of park firms. In fact, a firm’s ability to innovate and, consequently, to be successful seems to be related to its capacity to find and retain employees with relevant skills. This study analyses five case studies on three Swedish Science Parks and demonstrates the importance of the relationship with stakeholders to ensure support and the adequate development of attracting talent to Science Parks. Also, this study showed that the studied parks carry out different activities to attract talent, and the involvement of government agents and the local university proved to be essential for developing such activities.
