Pro-cop group Blue Lives Matter is petitioning Mayor de Blasio and Gov. Cuomo to overturn a “disgraceful” Manhattan community board decision not to honor the first NYPD officer killed in the Iraq War with a street renaming.

The group launched the petition on change.org following a story in the Sunday Post that Community Board 1 rejected a ceremonial street renaming for Staff Sgt. Jimmy McNaughton, a 27-year-old Army Reservist whose life was cut short by a sniper’s bullet in August 2005.

As of Saturday more than 5,200 people had signed the petition.

The Tribeca-based transit cop’s fellow officers and family lobbied to “co-name” West Broadway between Lispenard and Canal streets “James McNaughton Way.” But Community Board 1 voted down the proposal last month.

McNaughton’s dad, Bill, 63, suspects some of the board members are anti-cop and anti-military.

“It’s disgraceful,” Blue Lives Matter founder Joseph Imperatrice told The Post, saying “a tiny gesture would mean so much for the family.”
