Greatest Hits 3 is the third compilation album by American country music singer Tim McGraw.

However, the album does include two songs not previously released on any of McGraw's albums: "Find Out Who Your Friends Are" (a number one collaboration with Tracy Lawrence and Kenny Chesney, also featured on Lawrence's 2007 album For the Love) and "Nine Lives", a collaboration with Def Leppard.

The album also features a live version of "Real Good Man" (2003).

On October 14, 2008, McGraw issued a statement regarding his disappointment with his record label's decision to release the compilation instead of a new studio record.

He then stated: "In the spirit of an election year, I would simply say to my fans, I'm Tim McGraw, and I don't approve their message.
