Jack Hargreaves OBE (1911–1994) was an English television presenter and writer whose enduring interest was to comment without nostalgia or sentimentality on accelerating distortions in relations between the city and the countryside, seeking – in entertaining ways – to question and rebut metropolitan assumptions about its character and function. He is remembered for appearing on How, a children's programme, which he also conceived, about how things worked or ought to work. It ran from 1966 on Southern Television and networked on ITV until the demise of Southern in 1981.
