The Hinlopen Strait () is the strait between Spitsbergen and Nordaustlandet in Svalbard, Norway. It is long and wide. The strait is difficult to pass because of pack ice. It is believed to have been named after Thijmen Jacobsz Hinlopen.
The northern part of the strait is called Nordporten, between Storsteinhalvøya and Mosselhalvøya. The southern part, called Sørporten, widens up between BrÃÂ¥svellbreen and the Bastian Islands.
