CCC Camp NP-4, also known as the Horse Concessioner Dormitory and the Climbing Concession Office, at Jenny Lake in Grand Teton National Park was the largest Civilian Conservation Corps camp in Grand Teton.

Located at the South end of Jenny Lake, the camp housed young men from 1934 to 1942, who worked on improvements to trails, campsites, employee housing, utilities and timber salvage at Jackson Lake.

The bathhouse became the base for Paul Petzoldt and Glenn Exum's Petzoldt-Exum School of American Mountaineering.
