The country music star played five nights in Croke Park last September.
The policing bill for Garth Brooks' five concerts in Croke Park last year was €380,000.
It makes it far and wide the most expensive event for policing held last year.
Brooks played in front of crowds at Croke Park five times, with security and Gardaí present at the concerts.
Gardaí are known to charge for policing services at the events - with promoter Aiken Promotions agreeing a fee beforehand.

The second most expensive concerts to police were six gigs held at Malahide Castle in Dublin.
The concerts, held between June 14th and 25th, featured the likes of Lewis Capaldi and The Killers and cost almost €272,000 for security and policing.
Other live events, which cost around a quarter of a million to police, included Longitude Festival in Marlay Park and the National Ploughing Championships.
