The deal between brewer SAB Miller and the R&A, which runs the tournament, will start with the 2009 Open at Turnberry in July.
Nick Miller, managing director Miller Brands UK, said: "The relationship with the Open is a fantastic showcase for Pilsner Urquell.
"It enables us to offer our customers some exciting promotional activity that will help them to reward their consumers and build business."
The agreement will see Pilsner Urquell served in all public and VIP hospitality facilities. In addition, SAB Miller companies around the world will be able to use the association with the Open in advertising, promotions, ticketing and hospitality.
