The Rothschild banking family of Naples (Italian: Famiglia di banchieri Rothschild) was the Neapolitan branch of the Rothschild family. It was founded by Carl Mayer von Rothschild (1788–1855), who was sent to the Kingdom of the Two Sicilies from Frankfurt in 1821.

Endogamy within the family was an essential part of the Rothschild strategy in order to ensure control of their wealth remained in the family's hands. Through their collaborative efforts, the Rothschilds rose to prominence in a variety of banking endeavors including loans, government bonds, and trading in bullion. Their financing afforded investment opportunities and during the 19th century, they became major stakeholders in large-scale mining and rail transport ventures that were fundamental to the rapidly expanding industrial economies of Europe.

By 1820, N M Rothschild & Sons bank was already operating successfully in London, England, de Rothschild Frères in Paris, and S M von Rothschild in Vienna, Austria where Salomon Mayer von Rothschild became a powerful ally of Austria's Prince Klemens Metternich. In March 1821, in support of King Ferdinand I of the Two Sicilies, the Austrian army entered the Sicilian Kingdom and occupied Naples. This event opened the door to the Rothschild interests and Carl von Rothschild was sent to Naples where he established C M de Rothschild & Figli to operate as a satellite office to the Rothschild banking family of Germany headquarters in Frankfurt am Main.
