Fred Sandback (August 29, 1943 – June 23, 2003) was an American minimalist conceptual-based sculptor known for his yarn sculptures, drawings, and prints.

The artist's early interest in stringed musical instruments led him to make dulcimers and banjos as a teenager.

[3] Though he employed metal wire and elastic cord early in his career, the artist soon dispensed with mass and weight by using acrylic yarn.

[4] His yarn, elastic cord, and wire sculptures define edges of virtual shapes that ask the viewer's brain to perceive the rest of the form.

Sandback's work was the subject of an extensive survey exhibition organized in 2005 by the Kunstmuseum Liechtenstein, Vaduz (which traveled to the Fruitmarket Gallery, Edinburgh and the Neue Galerie am Joanneum, Graz, in 2006).
