What was the name of Metallica's first tour directly supporting The Black Album?

Metallica's first tour directly supporting The Black Album was the Wherever We May Roam Tour.

The tour followed the album's August 1991 release and took Metallica through an extensive series of dates in support of its new material. Its name came from the Black Album song “Wherever I May Roam,” one of the record's later singles and a song closely associated with the band's touring identity.

The tour formed part of a particularly busy period for Metallica. The band also appeared on the Monsters of Rock bill and later performed at the Freddie Mercury Tribute Concert, where it played “Enter Sandman,” “Sad but True,” and “Nothing Else Matters.” Those appearances are related to the same era but are not the tour's official name.

A common mix-up is using Damaged Justice, which supported ...And Justice for All, or World Magnetic, which supported Death Magnetic. The Wherever We May Roam Tour is specifically linked to The Black Album and lasted roughly 14 months across multiple countries.
