The following is a list of major terrorist attacks and arrests that have been connected to or have been claimed in reliable sources to be inspired by the Islamic State (IS), also known by other names. Between June 2014, when the group self-proclaimed itself to be the Islamic State, and February 2018, IS has often made claims of responsibility over 140 terrorist attacks in 29 countries outside Syria and Iraq, that were "conducted or inspired" by the group, while the evidences of those claims are not verified. Hundreds of other attacks were also carried out since 2018.
