Best-Selling Pink Floyd Album in the US by Certified Units

The Dark Side of the Moon is Pink Floyd’s best-selling album in the United States by certified units. The RIAA has awarded it 15x Platinum, meaning 15 million copies sold — each unit counts as one album, not per disc.

The Wall is often cited as a contender, but its 23x Platinum certification reflects a double album, so each sale counts as two units. That equates to roughly 11.5 million actual albums, putting it behind Dark Side by about 3.5 million copies.
