Rainer Maria is an emo/indie rock band formed in Madison, Wisconsin in 1995. Bassist Caithlin De Marrais, guitarist Kaia Fischer, and drummer William Kuehn formed the band in the late summer of 1995 and named the band after the German poet Rainer Maria Rilke.

They're known for their poetic lyrics and resounding metaphors. The lineup never changed during their eleven-year career.In its earlier days, the band had duel vocals performed by De Marrais and Fischer; later, De Marrais would become the lead vocalist in the majority of their songs.

The band's many tours and intimate live shows at venues such as Brooklyn's Northsix (now Music Hall of Williamsburg), Washington, D.C.'s The Black Cat, Bowery Ballroom in NYC, and Chapel Hill's Cat's Cradle helped to grow its fan base and fuel album sales.

On November 6, 2006, the band announced, through Pitchfork Media, that the December 16th show at New York City's Bowery Ballroom would be their last. They played one more show on December 17th at Northsix, which De Marrais referred to as "home" because it also served as the band's rehearsal space.

The band reformed in 2014 with a reunion show at Bowery Ballroom on December 31. Additional shows were added for February 14 and April 18, 2015 at Lincoln Hall in Chicago and Union Transfer in Philadelphia, respectively.

No other events have been announced as of yet.
