"À Tout le Monde" is a song by American heavy metal band Megadeth, featured on their 1994 studio album Youthanasia. It was released as a single on February 1995 through Capitol Records. The song was later remade and reissued as "À Tout le Monde (Set Me Free)", featuring Cristina Scabbia of Lacuna Coil, on Megadeth's 2007 studio album United Abominations.

The music video for "A Tout le Monde" was banned by MTV, who claimed it was pro-suicide. However, in an interview conducted around 1994, Megadeth frontman Dave Mustaine stated:

It's not a suicide song. What it is, it's, you, it's when people have a loved one that dies and they end on a bad note, you know, they wish that they could say something to them. So this is an opportunity for the deceased to say something before they go. And it was my impression of what I would like to say to people, if I had say, 3 seconds to do so in life before I died I'd say to the entire world, to all my friends, I love you all, and now I must go. These are the last words I'll ever speak, and they'll set me free. I don't have to say I'm sorry, I don't have to say I'm going to miss you, or I'll wait for ya. You know, I'll just say I loved you all, good, bad, indifferent, I loved you all.

"À tout le monde" is French for "To all the world" or "To everyone". The song's chorus, "à tout le monde, à tous mes amis, je vous aime, je dois partir", translated to English is respectively: "To everyone, to all my friends, I love you, I have to leave". The original release of the track does not feature a grave accent on the letter "à" anywhere within the liner notes, lyrics or cover art; this was later rectified on the 2007 version.

Kimveer Gill, the man behind the Dawson College shooting in September 2006, was a fan of the band. In his blog on VampireFreaks.com on the day of the attack, he had mentioned the song. This led Megadeth to be blamed by many watchdog groups for the shooting. In a performance in Montreal on September 27, shortly after the attack, Mustaine said to the crowd:
