Adelaide of Auxerre (born between 865[1] and 870, died between 928 and 929) was a Duchess consort of Burgundy by marriage to Richard, Duke of Burgundy, and had the title Countess of Auxerre, possibly as ruling Count.

She was the daughter of Conrad II, Duke of Transjurane Burgundy.

[2] In 888, she married Richard, Duke of Burgundy.

Adelaide is called Countess of Auxerre between 888 and 921.

It has been suggested that this was because she was given the County of Auxerre as her dowry.
