Rama IV Road ถนนพระรามที่ 4 , Bangkok

Rama IV Road (ถนนพระรามที่ 4 , usually shortened to ) is one of the major roads in Bangkok, Thailand. It connects Sukhumvit Road in the east to the intersection with Charoen Krung Road, Mittraphan Road and Song Sawat Road in the west.

Rama IV Road follows the course of a canal called Khlong Thanon Trong. The road was laid in 1857. It is therefore the first paved road in Thailand, surpassing Charoen Krung Road by four years. In the beginning, it did not have a name, but was simply called Thanon Trong ถนนตรง , which means "straight road". It was evenatually given a proper name, Rama IV Road, by King Rama VI in 1919. Khlong Thanon Trong was there until 1947, when it was drained for the widening of Rama IV Road.

Today the MRT Blue Line runs under Rama IV Road between the Hua Lamphong MRT Station and Queen Sirikit Convention Center MRT Station.
