Marta Astfalck-Vietz (née Vietz; 21 July 1901 – 14 February 1994) was a German photographer, social worker and painter associated with the Bauhaus movement.

As well as Ilse Bing, Lotte Jacobi, Marianne Breslauer, Germaine Krull, and Lucia Moholy she produced modernist images and portraits across the fields of avant-garde and commercial production, photojournalism, and fashion.

Marta Vietz was born in Neudamm (Neumark), Germany (now: Dębno, Poland), the daughter of a printer and head of the publishing house Klassische Kunst.

The family moved frequently during her schooling before settling in Berlin in 1912, where her father established a studio for fine art reproductions.
