A fetterlock is a sort of shackle that is a common charge in heraldry, often displayed in a way that resembles a padlock.

King Edward IV used a heraldic badge consisting of a fetterlock and a falcon. This was originally the badge of the first Duke of York, Edmund Langley, who used the falcon of the Plantagenets in a golden fetterlock. This was also used by his grandson Richard of York, 3rd Duke of York, who displayed the fetterlock opened.{{cite book|editor-first=Stephen|editor-last=Friar|title=A New Dictionary of Heraldry|location=London|year=1987|publisher=Alphabooks/A&C Black|isbn=0-906670-44-6|page=141}}
