Mettle is the second and final release from art rock band Hugo Largo. It was released by Brian Eno's record label, Opal, on January 1, 1989 and was supported by a European tour following its release. Mettle was produced by then-member and current electronic musician Hahn Rowe.

This was Hugo Largo's last album before their initial breakup, although a later 1990-91 lineup wrote and recorded new material for a third, never-released album.
