Transparency International (TI) Ireland is the Irish chapter of the worldwide movement against corruption (defined as the abuse of entrusted power for private gain). It was founded in 2004 and is part of the only global organisation dedicated to stopping corruption worldwide, working to create a "level playing field" for citizens, for business, for everyone.

Its vision is an Ireland that is open and fair – and where entrusted power is used in the interest of everyone. TI Ireland’s mission is to empower people with the support they need to promote integrity and stop corruption in all its forms.
