Lat Phrao Road (Thai: ถนนลาดพร้าว, RTGS: Thanon Lat Phrao, pronounced [tʰā.nǒn lâːt pʰráːw]) is one main road in Bangkok, Thailand. Despite its name the road does not run through the nearby Lat Phrao District. It begins at Phahonyothin Road, at the corners of the Lat Phrao Square, CentralPlaza Ladprao, and Union Mall in Chatuchak District, passes through Huai Khwang and Wang Thonglang Districts, and ends in Bang Kapi District. The road is serviced by two MRT Blue Line stations: Phahon Yothin and Lat Phrao. The MRT Yellow Line meanwhile runs along the road from YL01 Lat Phrao to YL08 Bang Kapi stations. The BTS Skytrain also serves this road at Ha Yaek Lat Phrao station.

This road was formerly known as "Bangkok-Bang Kapi Road" (ถนนกรุงเทพ-บางกะปิ) that ran through the area known as "Thung Bang Kapi" (ทุ่งบางกะปิ), a vast field on the northeast side away from the downtown about 16 km (9.94 mi); most of the fields were immense and some parts were jungles. Khlong Saen Saep that was dug during the reign of King Rama III also flowed through the area.

Lat Phrao Road was built in 1945, at the end of World War II. At that time it was just a dirt road that intersects with the Sam Yaek Saphan Khlong Saen Saep three-way junction. Over time, the road saw increasing development and was settled by various people.^[1]

Chok Chai 4 Road, or familiarly known as Soi Chok Chai 4 considered to be the most lively and alive quarter of this road. Also known as Soi Lat Phrao 53, the road includes a large community area with day and night markets, convenience stores, residences, police station and many more, as well as being able to link to other main roads such as Prasert Manukitch, Pradit Manutham, and Lat Phrao Wang Hin.
