Childline founder and TV presenter Esther Rantzen will open a new base for the helpline in Londonderry on Friday.
The ChildLine number is 0800 1111
The base, located at Queen's Quay, has been largely funded by the Department of Education.
It is the second base that Childline, a service provided by the NSPCC, has opened in Northern Ireland since 1999.
Childline relies heavily volunteers, and by opening a new counselling base in Derry, the service hopes to recruit more volunteer counsellors in the area.
The Childline number, which is a 24-hour, free-to-call service, is 0800 1111.
