Charlotta (Lotten) Johanna Jakobina von Plomgren (13 October 1831 – 20 July 1916), was a Swedish activist for civil defence.

Her youngest sister Jaquette Liljencrantz, would later run away to free herself from the harsh social control of her brothers and became a journalist in Copenhagen in Denmark.

[2] Lotten Liljencrantz's childhood was spent in Stockholm, partly in the Arvfursten Palace, after her father was appointed Marshal of the Court to King Oscar I in the 1840s.

[5] von Plomgren was chairman of the association for 30 years from its formation in 1884 until 1914, during which time it grew into one of Sweden's largest women's organisations.

[1] von Plomgren resigned from the board of the Swedish Women's Association for the Defence of the Fatherland in 1914 due to age and ill health.
