Exculpatory means clearing someone of blame or proving their innocence. When evidence is exculpatory, it shows that an accused person didn't do what they were accused of doing.

In a courtroom, exculpatory evidence might include a video showing the accused person was somewhere else when a crime happened, or a witness who saw someone else commit the act. If you were blamed for breaking a window but your friend found exculpatory evidence (like a neighbor's security camera showing a tree branch broke it during a storm), that evidence would clear you.

The opposite is inculpatory evidence, which suggests guilt rather than innocence. Defense lawyers search for exculpatory evidence to prove their client's innocence, while prosecutors look for inculpatory evidence to prove guilt.

You might encounter this word in legal contexts, mystery novels, or true crime stories. When someone says “the exculpatory evidence was overwhelming,” they mean there was so much proof of innocence that the accusation couldn't stand. The word captures that important moment when blame lifts and the truth emerges.
