Vitalogy is the third studio album by the American rock band Pearl Jam, released on November 22, 1994, on Epic Records. Pearl Jam wrote and recorded Vitalogy while touring behind its previous album Vs. (1993). The album's sound is more diverse than previous releases and consists of aggressive rock songs, ballads, and other stylistic elements, making it Pearl Jam's most experimental album at that period. Considered a departure from the grunge sound of the band's first two albums, the record focuses more on punk rock and hardcore styles in its production.

Pearl Jam has outsold and outlasted many of its contemporaries from the early 1990s, and is considered one of the most influential bands from that decade, dubbed "the most popular American rock and roll band of the '90s".
