Nancy Grace (born October 23, 1959) is a polarizing American legal commentator and former prosecutor who rose to fame as the host of HLN's Nancy Grace (2005–2016) and Court TV's Closing Arguments (2004–2007). Her career path was dramatically altered at age 19 when her fiancé, Keith Griffin, was murdered in a workplace shooting, prompting her to abandon a plan to teach English and instead pursue law at Mercer University. As a Special Prosecutor in Atlanta-Fulton County for nearly a decade, she focused on serial felonies, but her conduct drew serious sanctions: the Supreme Court of Georgia twice reprimanded her (including for withholding exculpatory evidence) and an 11th Circuit ruling found she "played fast and loose" with her ethical duties. She later transitioned to television, hosting shows like Trial Heat and the syndicated Swift Justice with Nancy Grace, and co-authored the book Objection! critiquing the criminal justice system. Known for her fierce, victims'-rights advocacy, Grace has been both praised for amplifying victim voices and criticized for her aggressive courtroom and media tactics, making her a significant and controversial figure in legal media.
