Coastal Liner is an Australian bus company operating services on the New South Wales Central Coast.

Established in 1986 after the acquisition of the Dooralong to Wyong bus run from local operator James McElhinney, Coastal Liner commenced operating under its original business name of Dooralong Valley Bus Service.

In 1988 owner Frank Caruna acquired the bus runs previously operated by Coast and Country (Len Robson), covering parts of Dooralong, Jilliby, Wyee and Warnervale, with the fleet increasing from two to three.

[1][2][3][4] In August 2018 the business was purchased by ComfortDelGro Australia with the routes absorbed by Hunter Valley Buses.

In 2014 new buses appeared in a variation to the Transport for NSW white and blue livery.
