克洛维三世，（法语：Clovis III，拉丁语：Chlodovechus III；670年－676年），自675年10月起为法兰克人墨洛温王朝的奥斯特拉西亚国王。

他可能是提乌德里克三世或克洛维二世的儿子，而奥斯特拉西亚贵族则宣称他是克洛泰尔三世的私生子，将他视为奥斯特拉西亚宫相胡夫尔德宣称的达格贝尔特二世之对立者。此时，纽斯特里亚宫相伊布汉加入克洛维的党派，并希望利用胡夫尔德对王位的申索与克洛泰尔三世及丕平二世对立。

Clovis III was the king of Austrasia from 675 to 676. Perhaps the son of Theuderic III or Clovis II, his Austrasian magnate supporters described him as an illegitimate son of Chlothar III. They placed him on the throne in opposition to the young Dagobert II, the claimant of Wulfoald, the mayor of the palace. At this time, Ebroin, once mayor of the palace of Neustria, escaped from his monastic imprisonment and joined the partisans of Clovis. He probably hoped to use the claimant to oppose Theuderic III and Pepin of Heristal in Neustria and Burgundy as well. Though Ebroin intended it, he never succeeded in displacing Theuderic and Pepin, though he was eventually recognised as mayor in his old post.
