- Remus Lupin: "A surprising number of people volunteered to come and get you."
- Alastor Moody: "Yeah, well, the more the better. We're your guard Potter."
- Remus Lupin: "We’re just waiting for the signal to tell us it’s safe to set off, we’ve got about fifteen minutes."

The Advance Guard were the members of the Order of the Phoenix that retrieved Harry Potter from 4 Privet Drive and escorted him to 12 Grimmauld Place on 6 August, 1995. This was done to provide Harry with a more secure environment after a pair of Dementors attacked him and Dudley Dursley in Little Whinging.
Prior to its arrival, the Advance Guard lured the Dursley family away from their house. Nymphadora Tonks fabricated a letter informing them that they were among the finalists for the All-England Best-Kept Lawn competition, and the family was heading to the awards ceremony when the Advance Guard arrived at 4 Privet Drive.
Out of the group, Harry only knew Lupin from before, and had spoken to the real Alastor Moody and Dedalus Diggle only briefly. This was Harry's first meeting with the remaining members, most notably Nymphadora Tonks and Kingsley Shacklebolt.
The Advance Guard and Harry travelled to Grimmauld Place by Broomstick, flying in formation with Tonks flying in front of Harry, Lupin underneath, Moody behind and the rest circling. There was a rear guard set up, so that if anything happened to the advance guard, the rear guard could take over, but this was, fortunately, not required.
Alastor Moody suggested the entire group travel above cloud level for better concealment, but he was overruled by Nymphadora Tonks, who protested they would get soaked with water. Later, he also suggested that they double back to ensure that they were not being followed, but Tonks once again screamed at him, and the group was saved by their arrival at Grimmauld Place.
Behind the scenes
- "The Advance Guard" is the title of chapter three in Harry Potter and the Order of the Phoenix.
- In the film adaptation of Harry Potter and the Order of the Phoenix, Remus Lupin, Dedalus Diggle, Hestia Jones and Sturgis Podmore were not a part of the Advance Guard, and the latter two did not appear in the film at all. The only person other than Lupin that Harry recognised was Moody, but given that Harry only met Barty Crouch Jr impersonating Moody, he would not be someone Harry would have trusted. Harry also calls him "Professor Moody" even though it wasn't actually him the previous year.
- In the film adaptation of Harry Potter and the Order of the Phoenix, the members are shown having crossed over River Thames in London.
- In an early script for the film adaptation of Harry Potter and the Order of the Phoenix, the Advance Guard are besieged by a pair of Dementors (possibly the same ones that attacked Harry and Dudley earlier that night) en route to Grimmauld Place. Moody and Tonks would have escorted Harry safely to Grimmauld Place, with the rest of the guard arriving shortly after once the Dementors were driven off. The same script also consistently and incorrectly refers to them as the "advanced guard".
