Music recording sales certification is a system of certifying that a music recording has sold a certain number of copies.

Almost all countries follow variations of the RIAA certification categories, which are named after the precious materials gold, platinum and diamond (silver is also used in some countries). The number of sales required for these awards varies depending on the population of the territory in which the album is released. Normally they are awarded only to albums released at least nationally and are awarded individually for each country in which the album is sold. Additionally, different sales levels may exist for different music media, such as albums, singles, or videos.

Originally applied to LP records, certification is now most commonly awarded for compact disc sales. Certification is usually awarded cumulatively, and it is possible for a single album to be certified silver, gold, and platinum in turn. An album that becomes platinum twice over is said to be "double platinum". An artist can also become a multi-platinum seller, if they have at least two albums both going single platinum, therefore meaning that they do not have an individual album selling these amounts.
