Geoffrey Posner (born 1949) is a British television producer and director. Posner has directed and produced some of Britain's most successful comedy shows since the early 1980s.
Starting off as a director on the satirical show Not the Nine O'Clock News, he then went on in 1982 to direct the groundbreaking BBC2 anti-sitcom The Young Ones. Working also as an assistant producer on that show, he went on to produce in the same year the unshown pilot of the Rowan Atkinson historical sitcom Blackadder. One of his biggest successes came in 1985, when he produced and directed the multi-award winning Victoria Wood As Seen On TV, a sketch show written by (and starring) the popular comedienne.
