Cox’s Bazar–Teknaf Marine Drive (Bengali: কক্সবাজার–টেকনাফ মেরিন ড্রাইভ) is an 80-kilometre-long road from Cox’s Bazar to Teknaf along the Bay of Bengal and it is the world’s longest marine drive.

In 1993, the then government finalized the 48 km long marine drive project for construction.

However, after the completion of the construction of a few kilometers, its work was terminated and later the incomplete road was washed away by the strong currents of the Bay of Bengal.
