The present invention relates to a pharmaceutical composition for preventing or treating liver fibrosis or liver cirrhosis, and more specifically, to a pharmaceutical composition for preventing or treating liver fibrosis or liver cirrhosis comprising a gold-containing agent. The pharmaceutical composition of the present invention, by comprising the gold-containing agent as an active ingredient, not only promotes M2-type transformation of macrophages but also inhibits the activation of stellate cells due to the increase of TREM-2 expression, and is thus expected to be effectively used as a pharmaceutical composition, a food composition, etc. , for preventing, treating, or ameliorating liver fibrosis or liver cirrhosis. Additionally, gold-containing agents, such as auranofin, sodium aurothiomalate, and aurothioglucose, have long been used for the treatment of a different disease (rheumatoid arthritis), and thus they have an advantage in that they are less likely to cause adverse effects.
