'''커피산'''(Caffeic acid)은 [[화학식]] C<sub>9</sub>H<sub>8</sub>O<sub>4</sub>을 갖는 [[유기 화합물]]이다. 폴리페놀이다. 황색 고체이다. 구조적으로는 [[하이드록시신남산]]으로 분류된다. 분자는 [[페놀|페놀성]] 및 [[아크릴산|아크릴성]] 작용기로 구성된다. 이는 [[바이오매스]]와 그 잔류물의 주요 구성요소 중 하나인 [[리그닌]]의 [[생합성]]에서 중간체로 모든 식물에서 발견된다.<ref name=Boerjan>{{저널 인용|doi=10.1146/annurev.arplant.54.031902.134938|title=Lignin biosynthesis|year=2003|last1=Boerjan|first1=Wout|last2=Ralph|first2=John|last3=Baucher|first3=Marie|journal=Annual Review of Plant Biology|volume=54|pages=519–546|pmid=14503002|url=https://biblio.ugent.be/publication/211742/file/4144786}}</ref> [[카페인]]과는 관련이 없다.
