Geoffrey Hayes is an English television presenter and actor, best known as the host of Thames Television's top-rated children's show Rainbow from 1973 to 1992. Before that, he had much other work, including a recurring role in BBC1's police drama Z Cars.

After Rainbow was cancelled, he continued to get work in television and pantomime, but it was not enough to earn a living as an actor, so he took a job working as a stock replenisher for the British supermarket chain Sainsbury's, before becoming a taxi driver, which he is still doing today.

Hayes has recently admitted he had not been wise with his money, and had little left by the time Rainbow came to an end. He also starred in a humorous television advert about investing money, making fun of his fall from the top.

In 1996, Hayes appeared in the video for "I'd Like To Teach The World To Sing" by Oasis tribute band, NoWaySis. He replicated the role as a taxi driver, just as Patrick Macnee had done in the Oasis video for "Don't Look Back In Anger".
