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

Ingeborg's marital engagement took place about 1234, in connection with her brother Eric XI reacquiring the Swedish throne from the usurper Canute II of Sweden, so that she and Eric could have the mighty House of Bjelbo as their ally.

Princess Ingeborg bore a vast number of children to her husband Duke Birger Jarl. In 1250, her brother died without heirs and her eldest son Valdemar was chosen to succeed Eric on the throne. Valdemar was chosen because he was her son, and her husband was made regent during his minority. Ingeborg thus became 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.
