Thames Television was a franchise holder of the British ITV television network, serving London on weekdays between 1968 and 1992. It was both a broadcaster and a producer of television programmes, making shows both for the local region it covered and for networking nationally across the ITV regions. The British Film Institute describes Thames as having "served the capital and the network with a long-running, broad-based and extensive series of programmes, several of which either continue or are well-remembered today."

Thames covered a broad spectrum of commercial public-service television, with a strong mix of drama, current affairs and comedy. The company's logo remains widely recognisable and was accompanied by a fanfare called "Salute To Thames", composed by Johnny Hawksworth.

It still operates today, although as an independent producer and on a much smaller scale. Following a merger by its owner FremantleMedia with Talkback Productions it is now known as Talkback Thames.
