Alfred A. Loeb State Park, State park on the Chetco River in Brookings, Oregon, US

Alfred A. Loeb State Park is a state park on the banks of the Chetco River in Curry County, Oregon, about 10 km from Brookings. Within its boundaries are 53 campsites, 3 rental cabins, a drift-boat launch and a day-use area. The head of a 0.75-mile trail here leads into the northernmost coastal redwood grove in the United States.

Alfred A. Loeb State Park was established on land bought from Alfred A. Loeb in 1948; in 1958 the State Board of Forestry donated 160 additional acres. The park lies on the banks of the Chetco River in Curry County, Oregon, and is administered by the Oregon Parks and Recreation Department.

The park's name honours Alfred A. Loeb, from whom the land was purchased in 1948. Visitors can see myrtlewood trees, a hardwood native to this corner of Oregon, and the Chetco River, where drift boats are launched. The 0.75-mile trail leads to the northernmost coastal redwood grove in the United States.

The park is open year-round with campgrounds and cabin rentals positioned along the river, plus basic facilities like showers and restrooms. Well-maintained trails guide visitors through the forest, and a boat launch provides direct water access for those wanting to explore by canoe or kayak.

The 0.75-mile trail from the park's day-use area reaches the northernmost coastal redwood grove in the United States. These trees grow about 400 miles north of the species' main range in California, a range limit that makes this small stand a notable botanical outpost.
