Peso dominicano has been the name of the currency of the Dominican Republic since 2010. Its symbol is "$", with "RD$" used when distinction from other pesos is required; its ISO 4217 code is "DOP". Each peso is divided into 100 centavos ("cents"), for which the ¢ symbol is used. With exception of the United States dollar, it is the only currency that is legal tender in the Dominican Republic for all monetary transactions, whether public or private.

The peso is the monetary unit of several Spanish-speaking countries in Latin America, as well as the Philippines. Originating in the Spanish Empire, the word peso translates to "weight". In most countries of the Americas, the symbol commonly known as dollar sign, "$", was originally used as an abbreviation of "pesos" and later adopted by the dollar. The dollar itself actually originated from the peso or Spanish dollar in the late 18th century. The sign "₱" is used in the Philippines.
