Cascade Canyon Barn, Historic barn in Grand Teton National Park, Wyoming, United States.

Cascade Canyon Barn is a National Park Service rustic log cabin on a stone foundation, with saddle-notched log corners and foundations buttressed at the corners to support the projecting log ends. Its original wide barn door has been filled in with windows and a personnel door. Inside are a main room with a small tack room in the southwest corner, built-in cupboards, a wood-burning cookstove, and a log-framed loft reached by a milled-lumber stairway. It stands 5 miles west of Jenny Lake.

The Cascade Canyon Barn was built in 1935 by the Civilian Conservation Corps to National Park Service standard plans. After an avalanche destroyed the Cascade Canyon patrol cabin in 1960, the barn was converted into a patrol cabin. It was listed on the National Register of Historic Places on August 18, 1998.

The barn shares its design and purpose with the Death Canyon Barn to the south in the park; the small differences between the two come from the materials on hand and the preferences of the crews that built them. Crews came from CCC camp NP3 at Hot Springs or camp NP4 at Jenny Lake.

The building is accessible via the Cascade Canyon Trail, which starts from the Jenny Lake area and offers relatively easy walking sections. Visitors should arrive early to allow sufficient time for the hike and to view the barn, especially during the busier summer months.
