Ingeborg was born the eldest daughter of King Eric X of Sweden and his wife, Richeza of Denmark. She lived her youth in exile in Denmark, after her brother had been deposed by his guardian and regent in 1229.

Ingeborg Eriksdotter's marital engagement took place in about 1234 in connection of her brother Eric XI resuming the Swedish throne from the 'usurper' Canute II of Sweden, to have the mighty House of Bjellbo as their allies.

Princess Ingeborg bore a vast number of children to her husband dux Birger Jarl. In 1250, her brother died without heirs and her eldest son Valdemar was chosen to succeed Eric on the throne; her son was chosen because he was her son, and her husband was made regent during his minority. Ingeborg thereby became the King's Mother and first lady of the royal court.

Ingeborg is recorded to have inherited her brother Eric's private property upon his death, as his only living sibling. Even in her forties, she continued to give birth to children, and her death is believed to have occurred because of childbirth complications, possibly giving birth to twins.
