Richard Oliver Postgate (12 April 1925 – 8 December 2008), generally known as Oliver Postgate, was an English animator, puppeteer and writer.

He made several series of children’s programmes for British television. They all became very popular. They include Pingwings, Pogles' Wood, Noggin the Nog, Ivor the Engine, Clangers and Bagpuss. They were all made by Smallfilms, the company he set up with Peter Firmin. They were shown on the BBC between the 1950s and the 1980s, and on ITV from 1959 to the present day. In a 1999 poll, Bagpuss was voted the most popular children's television programme of all time.
