The Shanghai Tunnels, less commonly known as the Portland Underground, are a group of passages running underneath Old Town/Chinatown down to the central downtown section of Portland, Oregon, United States. The tunnels connected the basements of many downtown hotels and bars to the waterfront of the Willamette River. They were built to move goods from the ships docked on the Willamette to the basement storage areas, which allowed businesses to avoid streetcar and train traffic on the streets when delivering their goods.
Historians have stated that although the tunnels exist and the practice of Shanghaiing was sometimes practiced in Portland and elsewhere, there is no evidence that the tunnels were used for this (and no evidence for Portland being a center for this kind of practice).
