Marial is an unincorporated community and the site of a former post office in Curry County, Oregon, United States. Located along the Rogue River about 48 miles (77 km) from its mouth on the Pacific Ocean, the area was home to Takelma Indians, then to white and Karok settlers, before becoming part of a designated wilderness. Buildings preserved at the Rogue River Ranch pioneer farm complex, listed on the National Register of Historic Places, represent the former center of Marial. Nearby are the Tucker Flat Campground and a riverside lodge named Marial.
Marial is in the Klamath Mountains in the Rogue River – Siskiyou National Forest. The nearby Lower Rogue River Trail, a National Recreation Trail, runs roughly parallel to the river between Grave Creek and Illahe through the Wild Rogue Wilderness. The 36-mile (58 km) stretch of the river between Grave Creek and Illahe is designated Wild and Scenic and is "one of the best-known whitewater runs in the United States". Marial is about 23 miles (37 km) downstream of Grave Creek and 13 miles (21 km) upstream of Illahe by water.
