It’s a huge achievement for the county considering there is just seven athletes on the team.
Both 800 metre runner Darren McBrearty from Letterkenny AC and pole vault specialist Tori Pina from Finn Valley will be hoping to impress having been chosen.
Another two Donegal athletes have also been chosen to represent Ireland in the European Walking Championships in Portugal in May.
Both Brendan Boyce of Milford and Jeff Cassin will be hoping to finish high in the rankings in the 50km event.
Athletics coach Patsy McGonagle said the selection of the athletes is recognition of their great strides in recent months.
The selection also comes just a day after Letterkenny athlete Mark English destroyed the field at Belfast Odyssey Arena to win the 800 metre event.
