Which logical fallacy means to attack the character of your opponent rather than their arguments?

The logical fallacy that means to attack the character of your opponent rather than their arguments is called "Ad hominem." This fallacy occurs when one focuses on personal traits, actions, or beliefs of their opponent instead of addressing the substance of their argument. By attacking the person making the argument, rather than engaging with the merits of the argument itself, the fallacy of Ad hominem seeks to discredit the opponent's character in order to undermine their viewpoint.
