Qu Shui Liu Shang 曲水流觴 (Floating Wine Cups Along a Winding Stream) is a traditional Chinese scholarly gathering in which wine cups were set afloat on a winding stream. Participants seated along the banks would drink and compose poetry when a cup stopped before them. Originating in ancient China and famously associated with the 4th-century Orchid Pavilion gathering, it became a symbol of literary elegance, friendship, and refined leisure.

「曲水流觴」是中國古代文人雅集的一種形式。酒杯隨蜿蜒曲折的溪流漂行，文士分坐水畔，酒杯停在誰的面前，便由誰飲酒賦詩。此俗源遠流長，尤以四世紀王羲之等人在蘭亭舉行的修禊雅集最為著名，後世遂以「曲水流觴」象徵文人風雅、知己交遊與宴飲賦詩之樂。
