Bayraklı Tunnels (Turkish: Bayraklı Tünelleri), formerly Karşıyaka Tunnels, are two motorway tunnels in series located on the İzmir's northern beltway, motorway O-30 E87, in Bayraklı district between Karşıyaka and Bornova of Izmir Province, western Turkey.

The tunnels were built by Kutlutaş-Dillingham Consortium, and the construction completed on 30 April 1999. However, the construction of the motorway lasted until 2007. Along with the motorway, the tunnels were opened to traffic on 19 January 2007. The official opening took place in presence of Prime Minister Recep Tayyip Erdoğan on 4 February 2007.

Named initially Karşıyaka Tunnels, they were renamed later to Bayraklı Tunnels upon the request of the Bayraklı district's governor. The 320 and 317 m (1,050 and 1,040 ft) (Bayraklı-1) and 1,865 and 1,876 m (6,119 and 6,155 ft)-long (Bayraklı-2) twin-tube tunnels carry three lanes of traffic in each direction. Dangerous goods carriers are not permitted to use the tunnel. Instead, they have to use either of the given routes:

• Bornova exit-D550-Altınyol-Girne Boulevard-Karşıyaka Entry
• Bayraklı exit-street #1620/39-street #1620/41-street #1609-Kubilay avenue-Onur Neighbourhood Entry
