Rose City Antifa (RCA) is an antifascist group founded in 2007 in Portland, Oregon. A leftist group, it is the oldest known active antifa group in the United States. While anti-fascist activism in the United States dates back to the 1980s, Rose City Antifa is the first to adopt the abbreviated moniker antifa. Since 2016, Rose City Antifa is one of the nine chapters of the Torch Network coalition.
