Reclaim the Streets also known as RTS, are a collective with a shared ideal of community ownership of public spaces. Participants characterise the collective as a resistance movement opposed to the dominance of corporate forces in globalisation, and to the car as the dominant mode of transport.

Reclaim the Streets often stage non-violent direct action street reclaiming events such as the 'invasion' of a major road, highway or motorway to stage a party. While this may obstruct the regular users of these spaces such as car drivers and public bus riders, the philosophy of RTS is that it is vehicle traffic, not pedestrians, who are causing the obstruction, and that by occupying the road they are in fact opening up public space. The events are usually spectacular and colourful, with sand pits for children to play in, free food and music, however they have been known to degenerate into riots and violence.

Reclaim The Streets was originally formed by Earth First!
