Stop Islamisation of Europe (SIOE) is a pan-European counter-jihad organisation with the stated goal of "preventing Islam from becoming a dominant political force in Europe". It is a political interest group which has been active in Denmark and has conducted anti-Islamic protests in the United Kingdom. The group originated out of the joining of the Danish group Stop Islamisation of Denmark with English anti-Islam activists.
The group says that its aim is to oppose Islamic extremism; they have the motto "Racism is the lowest form of human stupidity, but Islamophobia is the height of common sense".
