In Flames is a Swedish heavy metal band, formed by guitarist Jesper Strömblad in Gothenburg in 1990 out of the Swedish death metal scene. Their lineup has changed several times, with vocalist Anders Fridén and guitarist Björn Gelotte being the only consistent members since 1995. In Flames helped pioneer melodic death metal along with fellow Swedish bands At the Gates and Dark Tranquillity. The band has sold over two million records worldwide.

During the band's early years, In Flames had a varying group of musicians recording with them, including many session musicians. By the release of Colony (1999), the group had established a stable lineup. Their sixth studio album Reroute to Remain (2002) showed the band moving toward a newer style of music that moved further away from melodic death metal and closer to alternative metal. This decision was criticized by fans of the group's heavier metal sound; however, it increased the band's mainstream audience and bolstered their album sales.

Since the band's inception, In Flames have released fourteen studio albums, three EPs, and two live DVDs, their latest release being their fourteenth studio album Foregone in 2023. In Flames has been nominated for ten Swedish Grammis Awards winning seven of them; including “Hard Rock/Metal Album of the Year” category in 2005 for Soundtrack to Your Escape, 2007 for Come Clarity, 2009 for A Sense of Purpose, and most recently in 2024 for Foregone.
