Willibrordus Adrianus Maria "Joost" Luiten (born 7 January 1986) is a Dutch professional golfer who plays on the European Tour.

Luiten was a member of the 2006 Dutch team that won the Eisenhower Trophy after he played his last five holes in six under par.

He made his first start at the Tusker Kenya Open, where he birdied the 72nd hole for a share of tenth place.

He returned from injury in late 2009 and played the start of the 2010 season on a minor medical exemption, securing his card for the rest of 2010 with a top-ten finish at the Joburg Open.

In November 2011, Luiten won his first tournament on the European Tour with a victory in the Iskandar Johor Open in Malaysia, which also gave him his highest world ranking position to that point, at 66th.

In the first half of 2016 Luiten collected eight top-10 finishes in 15 events, with second places in consecutive weeks at the Real Club Valderrama Open de España and the Shenzhen International.
