Ernst Pepping (12 September 1901 – 1 February 1981) was a German composer of classical music and academic teacher. He is regarded as an important composer of Protestant sacred music in the 20th century.

Pepping taught at the Spandauer Kirchenmusikschule and the Berliner Hochschule für Musik. His music includes works for instruments (three symphonies), the church (the motet Jesus und Nikodemus, the Missa Dona nobis pacem), and collections including the Spandauer Chorbuch (Spandau choir book) and the three volume Großes Orgelbuch (Great Organ Book), which provides pieces for the entire liturgical year.
