Orono (/ˈɒrənoʊ/ ORR-ə-noh) is a town in Penobscot County, Maine, United States.

They named it in honor of Chief Joseph Orono, a sachem of the indigenous Penobscot nation who long occupied this territory.

Sawmills on the rivers were powered by the water, and logs were floated downriver on the Penobscot for shipping and export from coastal ports.

Piney Knoll Conservation Area, situated alongside the Penobscot River, is known for its walking trails and bird-watching.

The University of Maine also owns a considerable amount of protected land in the town.
