An "Affirmation in Support of an Order to Show Cause to Punish for Contempt" is a sworn written statement (typically from a party or attorney) that provides factual evidence and legal arguments to justify the court's issuance of an Order to Show Cause, which requires the accused party to appear and explain why they should not be held in contempt and punished (e.g., fined or jailed) for willfully violating a prior court order.

This document is commonly used in jurisdictions like New York, where such motions to punish for contempt must often be brought by Order to Show Cause accompanied by supporting affirmations or affidavits detailing the violation.
