The GolfSixes Cascais is an unofficial money team golf tournament on the European Tour.

The inaugural edition was played at Centurion Club in St Albans, England in May 2017.

It featured a 32-player field consisting of 16 teams of two, each representing a nation, competing for a €1 million purse.

The top two teams from each group progress to the knockout stages – the quarterfinals, the semifinals, a 3rd/4th place playoff match and the final – all of which were contested on the second and final day.

The winner of each match is the team with the most holes won after a six-hole contest.
