The Terrorist Financing Convention (formally, the International Convention for the Suppression of the Financing of Terrorism) is a 1999 United Nations treaty designed to criminalize acts of financing acts of terrorism. The convention also seeks to promote police and judicial co-operation to prevent, investigate and punish the financing of such acts. As of October 2018, the treaty has been ratified by 188 states; in terms of universality, it is therefore one of the most successful anti-terrorism treaties in history.
