Leodegar of Poitiers (Latin: Leodegarius; French: Léger; c. 615 – October 2, 679 AD) was a martyred Burgundian Bishop of Autun.

Leodegar was an opponent of Ebroin, the Frankish Mayor of the Palace of Neustria, and the leader of the faction of Burgundian nobles.

[1] Leodegar was the son of a high-ranking Burgundian nobleman, Bodilon, Count of Poitiers and Paris and St. Sigrada of Alsace, who later became a nun in the convent of Sainte-Marie at Soissons.

[1] He spent his childhood in Paris at the court of Clotaire II, King of the Franks and was educated at the palace school.

[1] Shortly afterwards Leodegar became a priest, and in 650, with the bishop's permission, became a monk at the monastery of St Maxentius in Poitou.

[1] Around 656, Leodegar was called to the Neustrian court by the widowed Queen Bathilde to assist in the government of the united kingdoms and in the education of her children.

Leodegar also caused the public buildings to be repaired and the old Roman walls of Autun to be restored.

[4][5] When Childeric II was murdered at Bondi in 675, by a disaffected Frank, Theoderic III was installed as king in Neustria, making Leudesius his mayor.

At Ebroin's instigation, Leodegar's eyes were gouged out and the sockets cauterized, and his tongue was cut out.

Historically there was a custom among wealthy British merchants to sell in May, spend the summer outside of London, then to return on St Leger's Day.
