Opp'n stands for Opposition, a litigation abbreviation.

Citation abbreviation for a brief opposing a motion, as in "Pl.'s Opp'n at 7", meaning page 7 of the plaintiff's opposition. It is one of the standard court-document abbreviations listed in the Bluebook's Bluepages.

Example: Defendant's reply notes that plaintiff's Opp'n at 7 concedes the contract was never signed.

Usage notes

The usual sequence of motion papers is the motion and supporting memorandum, the opposition and the reply; some courts allow a sur-reply only with leave. Local rules set the deadline and page limit for each. Related Bluepages forms include Mot. (motion) and Mem. (memorandum).
