John Garlick Llewellyn Poulson (14 April 1910 – 31 January 1993) was a British architectural designer and businessman who caused a major political scandal when his use of bribery was disclosed in 1972. The highest-ranking figure to be forced out due to the scandal was Conservative Home Secretary Reginald Maudling. Poulson served a prison sentence, but continued to protest his innocence, claiming that he was "a man more sinned against than sinning".
