The lilangeni (plural: emalangeni, ISO 4217 code: SZL) is the currency of Eswatini and is subdivided into 100 cents.

It was introduced in 1974 at par with the South African rand through the Common Monetary Area, to which it remains tied at a one-to-one exchange rate.

The currency's name derives from emaLangeni, a term used to describe the ancestors of the Swazi people who migrated to Swaziland in the 18th–19th centuries.

[8] In 1981, the Central Bank of Swaziland took over paper money production, first issuing notes commemorating the Diamond Jubilee of King Sobhuza II.

On September 5, 2008, the Central Bank of Swaziland issued 100-, and 200-emalangeni notes to commemorate the 40th birthday of King Mswati III and the 40th anniversary of independence.
