The Governor-General of Papua New Guinea is the representative of Queen Elizabeth II, known in Tok Pisin as 'Missis Kwin', Papua New Guinea's head of state, performing the same duties as the Queen in the United Kingdom. The current Governor-General of Papua New Guinea is Sir Paulias Matane.

Unlike other Commonwealth realms, the Governor-General of Papua New Guinea is nominated by the country's Parliament, rather than by its Prime Minister, as is the convention elsewhere. If the Governor General is removed from office, the Speaker of the House of Papua New Guinea's Parliament becomes acting Governor General.
