Chatuchak Weekend Market, Weekend marketplace in Chatuchak district, Thailand

Chatuchak Weekend Market, known as JJ Market, lies on Kamphaeng Phet 2 Road in Bangkok and holds more than 15,000 stalls run by 11,505 vendors, arranged in 27 numbered sections. Ceramics occupy sections 11, 13, 15, 17, 19 and 25, while clothing fills sections 2–6 and 10–26. Aisles run under sloping roofs of brown wooden planks on metal beams, past stalls such as Warinan Ceramics with its blue boxes and round pots.

The marketplace opened in 1942 and relocated several times before arriving at its current site near Chatuchak Park in 1983. The move formed part of a government initiative to reorganize trade areas in Bangkok.

The name Chatuchak comes from the surrounding district, where vendors have filled weekends with crowded aisles and quick sales calls for decades. Visitors today see sellers arranging goods in narrow corridors while shoppers thread through stacks of textiles, ceramics and spices.

The market operates Wednesday to Sunday from 8:00 to 20:00, with the information centre (Gate 1) open Saturday and Sunday from 08:00 to 20:30. The MRT Blue Line stops at Kamphaeng Phet (western end) and Chatuchak Park (eastern end), while Mo Chit BTS station serves the eastern end. A first-aid room sits behind the administration building in section 27.

A clock tower in the center of the grounds was built in 1987 for King Bhumibol Adulyadej's 60th birthday and serves visitors as a landmark. Many use the tower to find their way between sections.
