Sigismund (died 524) is king of the Burgundians from 516 to his death.

He is the son of king Gundobad, whom he succeeds in 516.

Sigismund and his brother Godomar are defeated in battle by Clovis' sons and Godomar flees.

Sigismund is taken by Chlodomer, King of Orléans, where he is kept as a prisoner.

He is drowned in the village of St Pervay la Colombe, near Orléans.

Godomar then rallies the Burgundian army and wins back his kingdom.

Meanwhile, Chlodomer orders the death of Sigismund and marches with his brother Theuderic I, King of Metz, on Burgundy in 524.
