Helen Dahm (May 21, 1878 – May 24, 1968) was a Swiss artist and a follower of the expressionist movement.

Her early work included hand-colored, hand-pressed fabric prints, mostly expressionistic in style.

In 1938, by invitation of Meher Baba, Dahm came to live in his ashram in Meherabad, India and painted the interior murals in his would-be samadhi (tomb) that had been completed earlier that year.

[1] Her paintings are still viewable there today, as restored by American artist Dot Lesnik in 1989.

After this period, Dahm's work took an inspired religious turn, becoming occupied with imagery including expressionistic interpretations of paradise, the Pietà, the crucifixion of Christ and angels.
