John Victor Lindsay "Hoppy" Hopkins was a British photographer, journalist, researcher and political activist, and "one of the best-known underground figures of 'Swinging London' " in the late 1960s.

The British counter-culture or underground scene developed during the mid 1960s, and was linked to the hippie subculture of the United States. Its primary focus was around Ladbroke Grove and Notting Hill in London. It generated its own magazines and newspapers, bands, clubs and alternative lifestyle, associated with cannabis and LSD use and a strong socio-political revolutionary agenda to create an alternative society.
