Association P.C. (which means Association Pierre Courbois) was a band playing a combination of jazz, rock and avantgarde music, sometimes labelled the first European jazz-rock group. It was founded in 1969 by Dutchmen Pierre Courbois (drums) & Jasper Van't Hof (keyboards) and German Toto Blanke (guitar). The bassist varied, it was either the Dutch Peter Krijnen or the German Sigi Busch.

Their first album Earwax was released in 1970 under the name Association and co-credited to Pierre Courbois. It was followed by Sun Rotation in 1971 and live album Erna Morena in 1972, after which Jasper van't Hof left the band to join Jean-Luc Ponty's band. He was replaced by German pianist Joachim Kühn. Their third album Rock Around The Cock came out in 1973. The next year, their last labum Mama Kuku, was released, consisting of live recordings from 1973, featuring the American flautist Jeremy Steig. The band continued to tour until 1975.
