Unthank Park is named for DeNorval Unthank, a prominent African American doctor and community leader, who was one of the first black doctors in the state. It was acquired by the City of Portland in 1966 and named for Unthank in 1969. The park was rededicated in June 2011 in a ceremony honoring Unthank.
Amenities include a basketball court, baseball field, playground, and picnic tables.
Unthank Park is the namesake of the Unthank Park Hustlers, a street gang which operates in the surrounding neighborhood.
