Karl Popper

thumb|Het graf van Popper en zijn vrouw in Wenen Karl Raimund Popper (Wenen, 28 juli 1902 – Londen, 17 september 1994) was een Oostenrijks-Britse filosoof die algemeen wordt beschouwd als een van de grootste wetenschapsfilosofen van de 20e eeuw.

Daarnaast was hij een belangrijk sociaal en politiek filosoof, een onversaagd verdediger van de liberale democratie en de principes van sociale kritiek waar deze op is gebaseerd, en een onwrikbaar tegenstander van autoritarisme. Hij is het bekendst geworden door zijn weerlegging van het klassieke model van wetenschap als een proces van observatie en inductie, zijn pleidooi voor falsifieerbaarheid als criterium om wetenschap van non-wetenschap te scheiden en zijn verdediging van de 'open samenleving'.
