Petersburg James A Johnson Airport is a public airport serving Petersburg, Alaska, a small fishing community on Mitkof Island in the Alexander Archipelago of Southeast Alaska. The airport is named in honor of James A. Johnson, a local figure recognized for contributions to the community. The airport is a vital transportation link for Petersburg, as the town is not accessible by road and relies on air and ferry service for connections to the broader region.

Due to its location in the Alaska Panhandle and the rugged surrounding terrain, the airport plays a critical role in providing year-round access for residents, medical transport, and cargo delivery.
