The 2005 WGC-World Cup took place 17–20 November at the Oceânico Golf on its Victoria Course in Vilamoura, Algarve, Portugal. It was the 51st World Cup and the sixth as a World Golf Championship event. The course was designed by Arnold Palmer and opened in 2004, the year before it hosted the World Cup. Eleven years after this tournament, in 2016, Dom Pedro Golf acquired the Victoria Course and four other Vilamoura courses from Oceânico Golf.
