About Petersburg

Petersburg (Tlingit: Gántiyaakw Séedi) is a census-designated place (CDP) in and essentially the borough seat of Petersburg Borough, Alaska, United States. The population was 3,043 at the 2020 census, up from 2,948 in 2010. The town is the headquarters of the Petersburg Indian Association, a federally recognized tribe of Tlingit people.

The borough encompasses Petersburg and Kupreanof, plus mostly uninhabited areas stretching to the Canadian–American border and the southern boundary of the City and Borough of Juneau. While the city of Petersburg ceased to exist as a separate administrative entity (the borough assembly created a service area to assume operation of the former city's services), the tiny city of Kupreanof remains separate within the borough.
