Quark, Strangeness and Charm is the seventh studio album by the English space rock group Hawkwind, released in 1977. It spent six weeks on the UK albums chart peaking at number 30. This is Hawkwind's seventh studio album, hence "The Hawkwind Part 7" title on the inner sleeve. It is the band's first album without co-founding member Nik Turner, and drummer Alan Powell had also departed. In addition, Adrian "Ade" Shaw from Magic Muscle replaced Paul Rudolph during the recording session. The music on this album is more pop-oriented than with their previous offerings. The cover is Hawkwind's only design by Hipgnosis, featuring internal photographs of Battersea Power Station processed by Richard Manning and graphics by Geoff Halpin.

The 2009 2CD re-issue of the album includes early versions of tracks with Rudolph's contributions. Rudolph's replacement was Adrian "Ade" Shaw, bass player from the group Magic Muscle, who had shared Hawkwind's management and been the support act on the 1972 Space Ritual tour. Shaw's introduction to the group was after the backing tracks had been completed, so he was required to overdub his bass parts onto the existing tracks. Drummer Simon King lamented "I only wish that I'd recorded the rhythm tracks with him in the first place. For me
