Oaks Bottom Wildlife Refuge is a 141-acre park in southeast Portland along the east bank of the Willamette River. The park is known for offering a home to a wide variety of birds. In 1988, the park became Portland's first wildlife refuge, and in 2004 the city's first migratory bird park.

The park includes open grassy areas, a large shallow lake, and mixed oak and maple woodlands. A popular hiking and biking path known as the Springwater Corridor runs along the Willamette River along the former Oregon Pacific Railway tracks. A mile-long hiking trail circles around the lake beneath the bluff. On the north end of the park are mixed woodlands, shrubs, and some open fields. Two islands, East and Hardtack, are located west of the north part of the refuge. Ross Island is a heron rookery.
