Can I use US Dollars or Euros in the Republic of the Congo?

The official currency is the Central African CFA franc (XAF). While some larger hotels in Brazzaville or Pointe-Noire might accept US Dollars or Euros for major bills, it is not common. For daily expenses like markets, taxis, and local restaurants, you will need to use CFA francs. It's best to exchange currency upon arrival.
