"Hero of the Day" is a power ballad by American heavy metal band Metallica from their 1996 album Load. The song was first recorded on December 13, 1995, and was the first song on Load to be recorded. The song was also Metallica's second single release from the album. A promotional video for the track was also filmed. It became their second consecutive number-one hit on the US Billboard Hot Mainstream Rock Tracks chart. It is one of the few Metallica songs written primarily in a major key.

According to article in Kerrang around time of Load release, the demo for the song is entitled "Mouldy" due to the main riff reminding James Hetfield and Lars Ulrich of a typical Bob Mould sound. The demo was recorded on December 10, 1994, one of the earliest demo recordings for the Load sessions (the first demo to be recorded was for Wasting My Hate on November 28, 1994).

This single is notable for including four Motörhead cover songs, recorded live direct to two-track at The Plant Studios during a rehearsal for Lemmy's 50th Birthday Party at the Whiskey A Go-Go, Los Angeles. These b-sides were later released on the second CD of the Garage Inc. compilation in 1998.

The music video for this song was directed by Anton Corbijn and features a drug-addled youth watching a television, with every channel featuring Metallica in some way. A Western movie titled Load is featured, starring Newsted and Hetfield, followed by a boxing match with Hetfield as coach, and Newsted and Kirk Hammett as the fighters. After a drink called "Load" is advertised by Ulrich and Hetfield in matching suits, a game show called "Hero of the Day" (which is a parody of Jeopardy!) is seen being played of which Jason Newsted is the host. Then, it cuts to the news with the anchorman played by Hammett and featuring a clip of Hetfield singing the lyrics to the song. A girl calls at the youth's house and they later try having sex, but the young man can't have an arousal, and visually disappointed, leans back in his bed. The girl later leaves. At the end, the youth passes out and dreams of tiny robot creatures, rendered in stop motion, emerging from his ear. He awakes from the dream and vomits into his toilet. [1]
