Diwali, the Hindu festival of lights, came to Bangkok primarily through the city’s growing Indian communities. Indian merchants and migrants established communities in Bangkok from the late 19th and early 20th centuries, with Phahurat (Little India) becoming an important centre of Indian religious, cultural and commercial life. Over time, Diwali evolved from a community religious observance into a broader celebration embraced by Bangkok’s multicultural society.

​

Today, Phahurat and nearby Khlong Ong Ang form the heart of Bangkok’s Diwali celebrations. Streets are decorated with colourful lights, rangoli and traditional motifs, while temples and community organisations hold prayers and ceremonies dedicated to deities such as Lakshmi and Ganesha. Visitors can enjoy Indian music, dance, cultural performances, handicrafts and festive markets. Along Khlong Ong Ang, the illuminated canal creates a particularly atmospheric setting, combining Diwali traditions with Bangkok’s historic urban landscape. This distinctive Thai–Indian celebration of light, bringing Hindu traditions, Indian heritage and Bangkok’s multicultural character together in one vibrant festival.
