Syagrius was a Roman general and the last ruler of a Roman rump state in northern Gaul, now called the Kingdom of Soissons. Gregory of Tours referred to him as King of the Romans. Syagrius's defeat by King of the Franks Clovis I is considered the end of Western Roman rule outside of Italy. He inherited his position from his father, Aegidius, the last Roman magister militum per Gallias. Syagrius preserved his father's territory between the Somme and the Loire around Soissons after the collapse of central rule in the Western Empire, a domain Gregory of Tours called the "Kingdom" of Soissons. Syagrius governed this Gallo-Roman enclave from the death of his father in 464 until 486, when he was defeated in battle by Clovis I.

The term Last of the Romans has historically been used to describe a person thought to embody the values of ancient Roman civilization – values which, by implication, became extinct on his death. It has been used to describe a number of individuals. The first recorded instance was Julius Caesar's description of Marcus Junius Brutus as the one with whom the old Roman spirit would become extinct.
