Patpong (Thai: พัฒน์พงษ์, "Phatphong") is an entertainment istrict 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, the city in fact has numerous red-light districts that are far more popular with Thai men. A busy night market aimed at tourists is also located in Patpong.
