Natalia Lach-Lachowicz (18 April 1937 – 12 August 2022) was a Polish artist who worked with paint, photography, drawing, performance, and video art.

[2][page needed] In 2018, the ZW Foundation was founded to preserve the works of Natalia LL as well as to provide a "place for exchanging scientific ideas and creative thoughts".

Her series, Consumer Art (1972–1975), depicts close ups of women eating and biting foods like bananas, sausages, and melons.

[2] After suffering from a severe illness in the late 1970s, Natalia LL began to delve into transcendental and mythological subjects, often photographing her performances.

In April 2019, after an anonymous complaint, the Polish National Museum in Warsaw removed from an exhibition works by Natalia LL, Katarzyna Kozyra, and the duo formed by Karolina Wiktor and Aleksandra Kubiak.
