Attorney Gloria Allred filed a dismissal of the case filed on behalf of Kristina Hagan on Monday. She wrote in an email that the case had been "resolved" but provided no further details.
Hagan sued Boreanaz and 20th Century Fox Television in July for more than $25,000 on sexual harassment and intentional infliction of emotional distress claims.
She claimed the actor repeatedly tried to kiss and fondle her several times after she appeared as an extra on the show in August 2009. The actor's spokeswoman denied the allegations.
A call to Boreanaz's attorney, Marty Singer, was not immediately returned.
Celebrity website TMZ.com first reported the dismissal.
