Johann Berenberg (born 12 March 1718 in Hamburg, died 2 March 1772 in Hamburg) was a Hamburg merchant banker. He was a co-owner of Berenberg Bank from 1748, with his brother, senator Paul Berenberg, and after the latter's death in 1768 the sole owner. The bank still bears his name (Joh. Berenberg, Gossler & Co.). He was also noted as an art collector and held several public offices in the city-state of Hamburg.
