The 2003 Churchill Cup was held between 14 June and 28 June 2003 in Vancouver, British Columbia, Canada. It was the inaugural year of the Churchill Cup. Three rugby union teams took part in the men's competition: Canada, England A and the USA.
A women's event involving the same teams also formed part of the event. This article concerns the men's event.
The teams played each other once in a round robin format, before the top two teams played in the Churchill Cup final.
