Nana Plaza, formerly Nana Entertainment Plaza, is an entertainment complex and red-light district in Bangkok, Thailand. Originally built as a shopping center, Nana Plaza occupies a three-story commercial building in the Khlong Toei District of Bangkok about 300 metres (330 yd) from the BTS Skytrain's Nana Station. It describes itself as the "worlds largest adult playground". Its name originates from the influential, property-holding Nana family, Lek Nana being the most prominent member.
Along with Soi Cowboy and Patpong, Nana Plaza is one of Bangkok's three most concentrated red-light districts. All attract primarily tourists.
