Ebba Månsdotter Lilliehöök of Kolbäck (13 January 1529, Upplo Manor, Västergötland – 29 September 1609 Lerjeholm i Angereds socken, Älvsborgs län), was a Swedish noble, landlord and county administrator, Countess of Raseborg, Baroness of Gräfsnäs and lady of Käggleholm.
[2] On 7 October 1548, she married the noble Sten Eriksson, Baron and Count Leijonhufvud (1518–1568) in the presence of the King at the Royal Palace in Stockholm.
Her spouse was the brother-in-law of King Gustav I and the brother of Queen Margaret Leijonhufvud, which gave them both an influential position at the royal court.
[4] She and her spouse participated in convincing the royal brothers to rebel against the King, financed by sister-in-law Martha Leijonhufvud, resulting in Erik XIV being replaced by John III in 1568.
She thereby became, alongside her sisters-in-law Brita and Martha Leijonhufvud, one of the five greatest fief holders in Sweden during the reign of John III.
