第一頸神經（Cervical spinal nerve 1, C1）是頸節脊神經的第一個分支^[1]，發源於寰椎（Atlas, C1）上方，主要承載運動纖維，但也有部分負責硬腦膜與枕骨大孔（英语：foramen magnum）感覺的腦膜支。此外，第一頸神經可能完全沒有背根（英语：Dorsal root of spinal nerve）或背根神經節。

C1與C2共同組成一個肌節，負責點頭與抬頭。

腹枝

第一頸神經腹枝與其他頸神經的腹枝共同組成頸神經叢（Cervical plexus）。

背枝

第一頸神經背枝又稱枕下神經（英语：Suboccipital nerve），支配枕下肌群（英语：Suboccipital muscles）。

頭後小直肌（英语：Rectus capitis posterior minor muscle）
頭後大直肌（Rectus capitis posterior major）
頭上斜肌（英语：Obliquus capitis superior muscle）
頭下斜肌（英语：Obliquus capitis inferior muscle）
