85% of the ISPCC's budget comes from fundraising and today its holding its first ever national collection day.
The charity's 24 hour helpline receives calls from one thousand children every day.
Volunteers will be out across the country today shaking buckets and collecting change.
ISPCC Interim CEO Caroline O'Sullivan says its important as many people as possible support.
"Try and dig as deeply as you can, to think of all those children who need a listening ear who need someone to be there to listen to them and to believe them, and we're asking the public to support us in that way."
