'''디벤질리덴아세톤'''(dibenzylideneacetone, dibenzalacetone, 줄여서 dba)은 공식 C<sub>17</sub>H<sub>14</sub>O를 갖는 [[유기 화합물]]이다. 밝고 노란 고체이며 물에 녹지 않지만 에탄올에는 녹는다. 디벤질리덴아세톤은 [[자외선 차단제]](선크림)를 이루는 요소로 쓰이며, 또 [[유기금속화학]]의 [[리간드]](이를테면 [[트리스(디벤질리덴아세톤)디팔라듐(0)]])로 쓰인다. 이 경우 이것은 [[트리페닐포스핀]]과 같은 더 강한 리간드로 쉽게 바뀌는 불안정한 리간드가 되므로 [[팔라듐]](0) 화학물로의 유용한 엔트리 포인트를 제공하게 된다.
