Elisabeth Berenberg (born 2 December 1749, died 16 January 1822) was a Hamburg heiress, grand burgheress, merchant banker and a member of the illustrious Berenberg family. She was the last male line member of the Dutch-origined Berenberg family, and ancestor of the Berenberg-Gossler family which now owns Berenberg Bank.

She was the daughter of Johann Berenberg (1718–1772) and Anna Maria Lastrop (1723–1761). Her grandfather Rudolf Berenberg was elected a Senator in 1735 and her great-grandfather Cornelius Berenberg had become an hereditary grand burgher in 1684. Her only brother Rudolf Berenberg (1748–1768) was possibly mentally ill and died at 20 in Suriname, where his father had sent him,[1] and her uncle, Senator Paul Berenberg (1716–1768), died without heirs in the same year. Elisabeth Berenberg thus remained as the only heiress of Berenberg Bank. In 1768, she married Johann Hinrich Gossler, who had joined Berenberg Bank as an apprentice, and her father made Gossler a partner in 1769. After Johann Berenberg's death, Gossler became the sole owner and head of the bank. The historian Percy Ernst Schramm describes their marriage as a marriage of convenience; she was not considered beautiful, but was intelligent, cultivated, kind, spoke many languages (including Latin) and became an exemplary wife and mother. She survived her husband by 32 years and after his death managed the firm together with her son-in-law until 31 December 1800, from which point the company was run by her son-in-law and her son alone.[2][3] The company's name was changed to Joh. Berenberg, Gossler & Co. in 1791.

She was the mother of Anna Henriette Gossler, who married Ludwig Erdwin Seyler, and of Senator Johann Heinrich Gossler. Her son-in-law, Seyler, became a partner in 1788 and head of Berenberg Bank in 1790. Her son Johann Heinrich Gossler joined the bank as a partner in 1798. Her grandson Hermann Gossler (1802–1877) became First Mayor and President of the Senate (head of state), whereas her great-grandson, Baron Johann von Berenberg-Gossler, was granted the name Berenberg-Gossler by the Senate of Hamburg in 1880, and subsequently ennobled by Prussia in 1888 and raised to baronial rank in 1910. From 1793 until her death in 1822, she used the manor house Stavenhagenhaus as summer residence.
