The Thaksin Express (Thai: รถด่วนพิเศษทักษิณ) is an express train run by the State Railway of Thailand (SRT) between Bangkok and Su-ngai Kolok, a border town in Narathiwat Province and the end of the southern rail line. Thaksin is a Thai word for 'south' (from the Sanskrit word dakshin), thus this train is referred to as the "Southern Express". The train's passenger cars include 1st- and 2nd-class air conditioned sleepers, 2nd-class fan sleepers, 2nd-class fan seating coaches, 3rd class air conditioned and fan seating coaches, and a dining car.

The train passes through cities and towns along the western edge of the gulf coast of southern Thailand on the upper Malay Peninsula. These include Nakhon Pathom, Hua Hin, Surat Thani, Hat Yai, Yala, and Su-ngai Kolok. Although the rail line is connected to the Malaysian rail system towards Rantau Panjang Station, there is no cross-border service on this route.
