A German Requiem, to Words of the Holy Scriptures, Op. 45 by Johannes Brahms, is a large-scale work for chorus, orchestra, and soprano and baritone soloists, composed between 1865 and 1868. It comprises seven movements, which together last 65 to 80 minutes, making this work both Brahms's longest composition and largest ensemble-work. A German Requiem is sacred but non-liturgical, and unlike a long tradition of the Latin Requiem, A German Requiem, as its title states, is a Requiem in the German language.

Johannes Brahms was a German composer, pianist, and conductor of the mid-Romantic period. Born in Hamburg into a Lutheran family, he spent much of his professional life in Vienna. He is sometimes grouped with Johann Sebastian Bach and Ludwig van Beethoven as one of the "Three Bs" of music, a comment originally made by the nineteenth-century conductor Hans von Bülow.
