Trident Television Limited was a British holding company with broadcasting interests.

It was created in 1970 to deal with the problem of fairly allocating airtime from a television transmitter at Bilsdale in North Yorkshire which straddled the catchment areas of two independent television companies. The transmitter itself was owned by the Independent Broadcasting Authority (IBA), the governing body of Independent Television (ITV). Due to the geographical nature of the area it served allocating the transmitter to either of the two closest broadcasting companies, Yorkshire Television and Tyne Tees Television, would have given one an advantage over the other in terms of selling commercial airtime.

The solution was to create a holding company for both stations. The role of Trident was thus to co-ordinate the selling of airtime in both television regions but with each company retaining its own separate identity and management control. Whilst it has been suggested that the original business plan was to include Anglia Television (which had similar issues with the Belmont transmitter whose area overlapped with that of Yorkshire) there is no evidence of this, and the third 'prong of the trident' is believed to have been the non-television interests of the company. It is likely that any involvement of Anglia would have been opposed by the IBA as it would have created a sales company with tremendous power in the ITV network. However in separate developments the Belmont transmitter was reallocated to Yorkshire in 1972.

In 1980 both Yorkshire and Tyne Tees had their contracts renewed but were forced to demerge. The Bilsdale transmitter was finally given to Tyne Tees as it was felt that Yorkshire had grown strong enough with the enlarged area it obtained through serving Belmont.

The demerger meant Trident's participation in ITV was effectively over. It continued to retain minority shareholdings in both companies which were eventually disposed of. Although it continued to receive rental funds from the studios and equipment leased to the two companies, it no longer earned funds from selling airtime.

The company then moved into the leisure and gaming industries, owning (amongst others) Windsor Safari Park, several London casinos and, for a short while, a chain of betting shops. In 1982 it merged with the leisure and brewing giant Grand Metropolitan plc.
