Hedwig Eleonora of Holstein-Gottorp (23 October 1636 – 24 November 1715) was Queen of Sweden from 1654 until 1660 as the wife of King Charles X Gustav. She served as regent during the minority of her son, King Charles XI, from 1660 until 1672, and during the minority of her grandson, King Charles XII, in 1697. She also represented Charles XII during his absence in the Great Northern War from 1700 until the regency of her granddaughter Ulrika Eleonora in 1713. Hedwig Eleonora was described as a dominant personality, and was regarded as the de facto first lady of the royal court for 61 years, from 1654 until her death.
