International Disability Alliance (IDA) is an alliance of networks that brings together over 1,100 organizations of persons with disabilities and their families from across eight global and six regional networks. They aim to promote the inclusion of persons with disabilities in global efforts to advance human rights and sustainable development. IDA supports these organizations in holding their governments accountable and advocating for change at local, national, and international levels.

As the most authoritative representation of persons with disabilities on the global level, IDA is composed of the foremost international disability rights organizations recognized by the United Nations System. Their work is centered around the effective implementation of the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD) and the 2030 Agenda and its Sustainable Development Goals. With member organizations worldwide, IDA represents an estimated one billion people living with disabilities, who are often marginalized and overlooked
