Otoyol 2 (), abbreviated as O-2, locally referred to as 2.Çevreyolu, TEM yolu or TEM in Turkish—which refers to Trans-European Motorway (), is a motorway in Istanbul, Turkey that forms the outer ring road of the city connecting European and Asian parts via the Fatih Sultan Mehmet Bridge. It starts in Mahmutbey East intersection on the European part, where the Avrupa Otoyolu () links, runs through the northern outskirts of the city passing over the Bosporus Strait, and terminates at the western end of the Anadolu Otoyolu (), before the toll plaza is situated. Otoyol 2 is toll-free, but a two-way toll collection practice has been implemented on the Fatih Sultan Mehmet Bridge. The O-2 motorway connects the European motorway in the west and with the Anatolian motorway in the east
