頸神經叢(Cervical plexus)是發源自前四對頸神經(英语:cervical spinal nerve)(C1-C4)前枝(英语:anterior rami)的一個神經叢[1][2][3],位于胸鎖乳突肌上部的深面中斜角肌和肩胛提肌的前方,位於脊椎橫突外側、脊椎前(prevertebral)肌肉內側,並與副神經、舌下神經、交感神經幹(英语:sympathetic trunk)形成吻合(anastomosis)。頸神經叢支配頭部後側與部分頸部的肌肉,各分支由頸部後三角(英语:Posterior triangle of the neck)邊界、胸鎖乳突肌中點上的頸神經點(英语:nerve point of neck)分岔出來。[2]
