The mission of the Colin Farrell Foundation is to help adult children with intellectual impairments by means of creative initiatives, education, and advocacy.

After walking alongside athletes during the Special Olympics World Summer Games in Ireland in 2003, Colin, a Dublin native, has long been an advocate for both the Angelman community and the larger intellectual disability community. He has since developed into an ardent spokesperson, supporter, and advocate for both the athletes and the organisation.

His recently established Foundation states: "Inspired by his two sons, Colin is excited and deeply humbled by the hope that the Colin Farrell Foundation can help those who the larger systems of governance have neglected."
