Opisthorchiasis is a parasitic disease caused by certain species of genus Opisthorchis (specifically, Opisthorchis viverrini and Opisthorchis felineus). Chronic infection may lead to cholangiocarcinoma, a cancer of the bile ducts.

Medical care and loss of wages caused by Opisthorchis viverrini in Laos and in Thailand costs about $120 million annually. In Asia, infection by Opisthorchis viverrini and other liver flukes affects the poorest people. Along with other foodborne trematode infections such as clonorchiasis, fascioliasis and paragonimiasis, opisthorchiasis is listed among the World Health Organization's list of neglected tropical diseases.
