Denny is an unincorporated community in rugged northwest Trinity County, California, United States. The area is known for its rich mining history, and is additionally popular for the isolation and seclusion that the Trinity Alps Wilderness offers. The community has no business that are currently open to the public, but there is still a strong residential community of people who maintain gardens, farmlands, and livestock. Currently there is a Denny Campground near the south end of the community that is maintained by the US Forest Service. In the 1970s there was a mining war between civilians and the Forest Service in which two people died. Actor Ed Flanders died there in 1995.More recently, the River Complex Fire of 2015 devastated large part near and around the Denny Community.
