Petter Carl Reinsnes was a Norwegian politician, mayor of the Sortland municipality, county mayor of Nordland, and a member of the Storting. Petter Ovald Karlsen was born in the Reinsnes district of Sortland municipality. He was elected into Sortland municipal council in the fall of 1931, and became mayor in 1935.

When the war was over, he returned to the Sortland municipality, and worked as mayor until 1959. His party, the Norwegian Labour Party, lost the municipal election in 1959, and Reinsnes consequently lost his position as mayor. Reinsnes retained his position on the municipal council. After the election in 1963, he was chosen to become the mayor again, and kept this position until 1975. He was also chairman of Nordland county council from 1945 to 1960, deputy county mayor from 1966 to 1970 and county mayor of Nordland in 1971.

During both terms, Reinsnes was a member of the Standing Committee on Foreign and Constitutional Affairs and the Enlarged Committee on Foreign and Constitutional Affairs. He campaigned for the construction of an agriculture school in Vesterålen, and he was a chairman for Vesterålens power group from the start in 1939 until his death in 1976. In the 1960s, he took the initiative to connect the islands in Vesterålen by a bridge. The Andøy and Kvalsaukan Bridges were opened in 1974, and Sortland Bridge was opened in 1975. Hadsel Bridge was opened in 1978, after his death. He was a chairman in Vesterålsbruene A/S from 1970 until his death. Reinsnes was also engaged in work to obtain an airport for Vesterålen.
