The International Conference on Climate Change (ICCC) is a conference series organized and sponsored by The Heartland Institute which aims to bring together those who "dispute that the science is settled on the causes, consequences, and policy implications of climate change." The first conference took place in 2008.

The Heartland Institute is an American conservative and libertarian 501(c)(3) nonprofit public policy think tank known for its rejection of both the scientific consensus on climate change and the negative health impacts of smoking.
