Willibrordus Adrianus Maria "Joost" Luiten (born 7 January 1986) is a Dutch professional golfer who plays on the European Tour.
After a failed bid for a tour card at Qualifying School he started his professional career on the EPD Tour where he claimed second place twice in just four starts. Because he was not in possession of a tour card Luiten was solely dependent on invites to play on the Challenge Tour.
After finishing sixth in the 2007 Challenge Tour rankings he received a European Tour card for 2008 and claimed two top 10 spots before injury curtailed his season.
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.
