Patpong (Thai: พัฒน์พงศ์, rtgs: Phat Phong) is an entertainment district in Bangkok, Thailand, catering mainly, though not exclusively, to foreign tourists and expatriates. While Patpong is internationally known as a red light district at the heart of Bangkok's sex industry, it is in fact only one of numerous red-light districts with some catering primarily to Thai men while others, like Patpong, cater primarily to foreigners.
A busy night market aimed at tourists is also located in Patpong.
