Tekkebak Tunnel (Turkish: Tekkebak Tüneli), is a highway tunnel constructed in Ordu Province, northern Turkey.
Tekkebak Tunnel is part of the Samsun-Ordu Highway within the Black Sea Coastal Highway, of which construction was carried out by the Turkish Nurol-Tekfen-Yüksel joint venture. The 170and-long twin-tube tunnel carrying two lanes of traffic in each direction is flanked by 261--long Kozbükü Tunnel in the west and 3805--long Ordu Nefise Akçelik Tunnel (named in honour of the late female engineer Nefise Akçelik) in the east on the same highway.
The tunnel was opened to traffic on 7 April 2007 by Turkish Prime Minister Recep Tayyip Erdoğan. Dangerous goods carriers are not permitted to use the tunnel.
