The Bank of Syria and Lebanon, from 1919 to 1924 Banque de Syrie, from 1924 to 1939 Banque de Syrie et du Grand-Liban, then Banque de Syrie et du Liban (BSL) from 1939 to 1963, was a French bank that was carved out from the Imperial Ottoman Bank following World War I and granted a central banking role in what would become Syria and Lebanon under French mandate and in the early years of the two countries' independence.

Banque du Liban is the central bank of Lebanon. It was established on August 1, 1963, and became fully operational on April 1, 1964. In 2023, Wassim Mansouri stepped up as interim governor of the Banque du Liban after Lebanon failed to name a successor to Riad Salameh, whose term finished in July 2023.
