What is the title of Pink Floyd's best-selling album?

Pink Floyd’s best-selling album is The Dark Side of the Moon.

Released in 1973, the album became a landmark of progressive rock through its seamless sequencing, studio experimentation, and themes of time, money, conflict, mortality, and mental strain. The core band—David Gilmour, Nick Mason, Roger Waters, and Richard Wright—developed much of the material through live performances before recording it.

The album’s famous cover, designed by Hipgnosis, shows white light passing through a prism and splitting into a rainbow. Its songs include “Money,” “Time,” “Us and Them,” and “The Great Gig in the Sky.”

A frequent confusion involves The Wall, which was also hugely successful and is Pink Floyd’s highest-certified album in the United States when its double-album format is counted. Worldwide, however, The Dark Side of the Moon is generally identified as the band’s best-selling release, with reported sales of roughly 45 million copies.
