Otoyol 33 (O-33), also known as the North Aegean Motorway, is a 55.2-kilometer toll road in western Turkey. It starts at the İzmir Beltway in Çiğli and runs north to Bergama, mostly parallel to the D550.

The construction tender was awarded on 15 February 2017 to a group of IC İçdaş, Kalyon, and Astaldi under a build-operate-transfer scheme lasting until 2027. Groundbreaking took place on 5 April 2017 in a ceremony with Prime Minister Binali Yıldırım and Transport Minister Ahmet Arslan. The motorway opened to traffic on 30 October 2019, costing about US$408.2 million.

Note: The O-33 designation used to refer to the Bursa Beltway, which is now part of O-5 and O-22.
