So ... is this good or bad news for Newcastle's Dutch players Daryl Janmaat and Tim Krul?
The 68-year-old only took over from Louis van Gaal after the 2014 World Cup, but the Dutch Football Association said in a statement on its official website that Hiddink would leave his role on July 1.
Holland only lie third in their Euro 2016 qualifying group, behind Iceland and Czech Republic.
Hiddink's contract had been due to run until Euro 2016.
