The Otoyol (Plural: Otoyollar) is the national network of controlled-access highways in Turkey. The term Otoyol translates to motorway while the literal meaning is auto-route. The Otoyol was first opened in 1973.

As of December 2024, there are 3,796 km of otoyol in service, the network passes through 28 provinces out of 81 in Turkey.

The system previously consisted of three separate networks; the Edirne-Istanbul-Ankara corridor, the Aegean network centred on İzmir and the Southeastern network centred on Adana. With the completion of the O-5 in 2019 and the extension of the O-21 in 2020, these three networks have since been connected. The network is expected to expand to 8,325 kilometres (5,173 mi) by 2053. The minimum speed limit on the Turkish otoyols is 40 km/h (25 mph) while the maximum speed is 140 km/h (87 mph).
