Ban Wanglih is a two-storey mansion in Bangkok, built in 1881 and which for a time was used as the family home of an influential Tae Chew businessman..

He belonged to the Wanglih Clan and ran the family business and networks, which maintained trade routes with Canton, Hong Kong, Singapore and Saigon, from here.

When the Wanglih business empire later expanded into rice milling it by 1920 had become one of Siam's largest rice millers and exporters. The mansion is built at the location of an old wharf, adjacent to the Lhong 1919 depots, which the family acquired in 1919.
