Dama con furetto: Ritratto di Lindsay Marie Clancy (Woman with a ferret: Portrait of Lindsay Marie Clancy) is an electronic painting based on Leonardo da Vinci's Lady with an Ermine (c. 1489–1491).

Lindsay Marie Clancy is a Massachusetts mother charged with the 2023 killings of her three young children on January 24, 2023, at the family's home in Duxbury, Massachusetts. She was 32 at the time and experiencing symptoms of postpartum psychosis and bipolar disorder, for which she was unsuccessfully treated for four months by multiple health care providers.

Her defense argued that she was not criminally responsible because of her mental illness. Her trial lasted nearly six weeks; after approximately 38 hours of deliberations over seven days, the jury remained divided 11-1, with a single holdout juror preventing a unanimous verdict. The Judge, William F. Sullivan, declared a mistrial on September 4, 2026.

The painting appropriates Leonardo's portrait of Cecilia Gallerani, painted in Milan circa 1489-1491. Her hair is arranged in the fashionable Renaissance coazzone, with a lenza, a narrow band worn across the forehead, securing a fine transparent veil. She is depicted here holding an albino ferret, rather than an undomesticated stoat or ermine (short-tailed weasel) referenced in later titles for Leonardo's original.

The image is painted from nearly 100 media fragments.
