The following is a list of best-selling albums by country. Depends on the measurement, record sales of albums are taken by estimations or certifications.
Note that some of the data are incomplete due to a lack of available published data from a number of territories, unlike the United Kingdom and the United States with recognized national measurement firms and certifying bodies such as Official Charts Company/British Phonographic Industry (BPI) and Nielsen SoundScan/Recording Industry Association of America (RIAA) respectively. Therefore, it is not an exhaustive list, so no rankings are given in certain cases.
