Marion Kavanaugh Wachtel (June 10, 1873/77 – May 22, 1954)[1][nb 1] was an American plein air painter in watercolors and oils.

She lived and worked with her artist husband Elmer Wachtel in the Arroyo Seco near Pasadena, California, in the early 20th century.

[2] She painted primarily figures and portraits in the east[5] and then changed to landscapes of the dramatic Californian and Southwestern terrain.

Her medium of choice was watercolor, but she began painting in oils after her husband’s death.

There were nearly 100 landscape paintings of California in the show made by the en plein air artists.
