松诺（拉丁语：Sunno）（350年－400年），380年－400年在位，法兰克国王。公元388年曾经入侵罗马帝国。

松诺和格诺鲍德、马尔科梅尔入侵罗马省份日耳曼和比利时。他们冲破了特里尔的防守，大肆屠杀，蹂躏了最肥沃的土地，威胁城市科隆。这次袭击后，大部分的法兰克人和他们的战利品回到莱茵河。有些法兰克人的留在比利时的森林里。当罗马大将南尼努斯和昆提努斯在莱茵河闻讯，他们袭击剩余的法兰克军队并杀死了许多人。战后，昆提努斯越过莱茵河在法兰克人自己的国家惩罚他们；但是，他的军队被法兰克军队围攻。一些罗马士兵被淹死在沼泽，剩余的被法兰克人杀死，只有少数回到自己的帝国。

Sunno was a leader (dux) of the Franks in the late 4th century that invaded the Roman Empire in the year 388 when the usurper and leader of the whole of Roman Gaul, Magnus Maximus was surrounded in Aquileia by Theodosius I.

The invasion is documented by Gregory of Tours who cited the now-lost work of Sulpicius Alexander. According to this account, Marcomer, Sunno and Genobaud invaded the Roman provinces Germania and Belgia. They broke through the lines and killed many people, destroyed the most fruitful lands and made the city of Köln panic. After this raid the main body of the Franks moved back over the river Rhine with their booty while some remained in the Belgian woods. When the Roman generals Magnus Maximus, Nanninus and Quintinus heard the news in Trier, they attacked those remaining Frankish forces and killed many of their number. After this engagement, Quintinus crossed the Rhine to punish the Franks in their own country, however his army was surrounded and beaten. Some Roman soldiers drowned in the marshes, others were killed by Franks, few made it back to their empire.
