The Days of Rage demonstrations were a series of violent actions taken over a course of three days in October 1969 in Chicago, organized by the Weatherman faction of the counterculture-era group Students for a Democratic Society.

The group planned the October 8–11 event as a "National Action" built around John Jacobs' slogan "bring the war home", which grew out of a resolution drafted by Jacobs and introduced at the October 1968 SDS National Council meeting in Boulder, Colorado. The resolution read, "The Elections Don't Mean Shit—Vote Where the Power Is—Our Power Is In The Street". It was adopted by the council, prompted by the effects of the 1968 Democratic National Convention protest activity in August and reflecting Jacobs's advocacy of direct action as political strategy.
