The British West Indies dollar (BWI$) was the currency of British Guiana and the Eastern Caribbean territories of the British West Indies from 1935 to 1965, when it was largely replaced by the East Caribbean dollar, and was one of the currencies used in Jamaica from 1954 to 1964. The monetary policy of the currency was overseen by the British Caribbean Currency Board (BCCB). The British West Indies dollar was never used in British Honduras, the Cayman Islands, the Turks and Caicos Islands, the Bahamas, or Bermuda.

Queen Anne's proclamation of 1704 introduced the gold standard to the British West Indies, putting the West Indies about two hundred years ahead of the East Indies in this respect. Nevertheless, silver pieces of eight continued to form an important portion of the circulating coinage right up until the late 1870s. In 1822, the British government coined 1/4, 1/8, and 1/16 fractional 'Anchor dollars' for use in Mauritius and the British West Indies (but not Jamaica). A few years later copper fractional dollars were coined for Mauritius, Sierra Leone, and the British West Indies.

The first move to introduce British sterling silver coinage to the colonies came with an imperial order-in-council dated 1825. This move was inspired by a number of factors. The United Kingdom was now operating a very successful gold standard in relation to the gold sovereign that was introduced in 1816, and there was a desire to extend this system to the colonies. In addition to this, there was the fact that the supply of Spanish dollars (pieces of eight) had been cut off as a result of the revolutions in Latin America where most of the Spanish dollars were minted. The last Spanish Dollar was in fact minted at Potosi in 1825. There was now a growing desire to have a stable and steady supply of British shillings everywhere where the British drum was beating. The 1825 order-in-council was largely a failure because it made sterling silver coinage legal tender at the unrealistic rating in relation to the Spanish dollar of $1 = 4 shillings and 4 pence. Interestingly it did succeed in Jamaica, Bermuda, and British Honduras because the authorities in those territories set aside the official ratings and used the more realistic rating of $1 = 4 shillings. The reality of the rating between the dollar and the pound was based on the silver content of the Spanish pieces of eight as compared to the gold content of the British gold sovereign.
