背侧运动前皮质（英语：dorsal premotor cortex）是灵长类动物额叶皮质中一个功能独特的皮质区或皮质群。解剖学研究证实，大多数顶叶输入到背侧运动前区皮质起源于上级顶叶小叶。然而，这些投射不仅来自5区的背侧，正如人们早就知道的那样，而且来自后顶叶皮层的新定义区域，这些区域与纹外视皮层直接相连。因此，背侧前运动皮层接收比以前接受的更直接的视觉输入。看来这个额顶叶网络的功能就像一个视觉计算器，它根据本体感受、视觉、凝视、注意力和其他信息进行计算，产生一个反映运动选择、准备和执行的输出。
The dorsal premotor cortex is a functionally distinct cortical field or group of fields in the primate frontal cortex. Anatomical studies have confirmed that most parietal input to the dorsal premotor cortex originates from the superior parietal lobule. However, these projections arise not only from the dorsal aspect of area 5, as has long been known, but also from newly defined areas of posterior parietal cortex, which are directly connected with the extrastriate visual cortex. Thus, the dorsal premotor cortex receives much more direct visual input than previously accepted. It appears that this fronto-parietal network functions as a visuomotor controller—one that makes computations based on proprioceptive, visual, gaze, attentional, and other information to produce an output that reflects the selection, preparation, and execution of movements.
