Eleonora Ziemięcka (ne Gagatkiewicz) (born 1819 in Jasieniec in Mazovia, died September 23, 1869, in Warsaw) - was a Polish philosopher and publicist.

She was educated by her grandmother, also Eleonor, who emphasized readings of contemporary romantic poets such as Adam Mickiewicz, Józef Bohdan Zalewski and Franciszek Karpiński.

Subsequently, she began contributing regularly to various periodicals, such as Tygodnik Polski, Magazyn Powszechny and Pierwiosnka, publishing literary works (short stories, fairy tales) and editorials.

Ziemiecka became associated with conservative Polish intelligentsia of Congress Poland who opposed the growing influence of Hegelism, seeing it as a threat to traditional values and social order.

In 1842 Ziemiecka founded a conservative-Catholic monthly journal Pielgrzym (Pilgrim) where she published literary, philosophical and political essays, as well as translations of French religious works.

At the same time she also criticized romance novels, as in her view these overstimulated the imagination, were too emotional, and led to detachment from reality which resulted in family strife and failures in life.

She based these arguments on a religious foundation, and the note was an extension of material first published in Zarys filozofii katolickiej ("Outline of Catholic Philosophy") in 1857.
