The port cities of Seattle and Gdynia have much in common. These commonalities prompted the formation of the Seattle-Gdynia Sister City Association (SGSCA), one of Seattle’s twenty-one sister cities. SGSCA is a 501(c)(3) organization, staffed entirely by volunteers who are committed to sharing and promoting business, cultural and academic exchanges between the two cities.

Sister Cities International awarded Seattle-Gdynia Sister City Association with the Innovation: Youth & Education, 2010 honor for its work on Gdynia Business Week.

The City of Seattle awarded Seattle-Gdynia Sister City Association with Best Overall Program, 2011 and 2006, as well as Best Single Project, 2010 for its work on Gdynia Business Week.
