Sillery is a former city in central Quebec, Canada. Located just west of old Quebec City, Sillery was among the many outlying municipalities amalgamated into an expanded Quebec City on January 1, 2002. Its former territory now forms part of the borough of Sainte-Foy–Sillery–Cap-Rouge. The name Sillery is still used to refer to the affluent neighbourhood. Sillery was named for Noël Brûlart de Sillery (1577–1640), Knight of Malta.
