Camp Pioneer, Boy Scout summer camp in Mount Jefferson Wilderness, Oregon.

Camp Pioneer is a Boy Scouts of America camp in the Mount Jefferson Wilderness area of Willamette National Forest, Oregon, operated by the Cascade Pacific Council. It sits around Pine Ridge Lake at 4,875 feet (1,486 m) at the base of Mount Jefferson, near the Pacific Crest Trail, south of Marion Forks and east of Oregon Route 22.

Cap Monroe, a Cascade Pacific Council councilman, founded Camp Pioneer in 1936 with Eagle Scouts from an Albany troop. In 2002 a forest fire closed the camp temporarily while the U.S. Forest Service used it as a command post; in 2003 crews protected it from the B&B Complex Fires.

The camp teaches practical outdoor skills such as water sports, hiking, and wilderness navigation to help young people build confidence and learn teamwork. Visitors can observe groups working together and supporting each other through challenges.

The camp operates during summer months from July through August and requires groups to have at least two adults accompanying youth participants. Staff members on site can provide guidance on activity schedules and help orient visitors to the different facilities.

The Cascade Ranger program takes participants aged 14 to 17 on extended backpacking trips near Mount Jefferson and Three-Fingered Jack peaks. These wilderness expeditions offer a chance to experience the high alpine environment away from the main camp facilities.
