Almost 500 of the children were under the age 11.
Over 3,300 children under the age of 15 got anti-depressant medication last year.
According to freedom of information files, it's a 55% increase on five years earlier.
These figures show the number of children who got anti-depressant medication in recent years.
They relate to prescriptions written under the Medical Card Scheme, the Drug Payment Scheme and the Long-Term Illness Scheme.
A total of 3,310 children under 15 got anti-depressants under these schemes last year.
That's 200 more than the year before - and nearly 1,200 more than in 2016.
Of the children prescribed anti-depressants last year, 495 were under the age of 11.
