The Squill Sifters were a group of Galactic Republic spies, slicers and codebreakers active during the Waymancy Storm of 7811 BBY. During the war with Waymancy Hollow, they worked to intercept and analyse Waymancy communications.

One of the Squill Sifters was the mother of the future Supreme Chancellor, Nagratha. On the Twenty-Fifth Anniversary of the end of the conflict, Nagratha gave a commemorative speech and singled out the Squill Sifters for their contribution to the Republic's victory.
