Youthanasia is the sixth studio album by American heavy metal band Megadeth, released on November 1, 1994, through Capitol Records. It is stylistically similar to their previous album, Countdown to Extinction (1992). The title is a play on words, implying that society is euthanizing its youth. The cover art features an elderly woman hanging babies by their feet on a seemingly endless clothes line, a direct reference to a line in the title track.

Youthanasia received positive reviews upon its release. It was commercially successful, peaking at number 4 on the Billboard 200 chart, and in 1995 was certified platinum for shipping one million copies in the United States. A remixed and remastered edition featuring several bonus tracks and detailed liner notes was reissued on July 27, 2004.
