Douglas (Manx: Doolish, pronounced [ˈdðuːlʲəʃ]) is the capital city and largest settlement of the Isle of Man, with a population of 26,677 (2021). It is located at the mouth of the River Douglas, and on a sweeping bay of two miles (three kilometres). The River Douglas forms part of the city's harbour and main commercial port. Douglas was a small settlement until it grew rapidly as a result of links with the English port of Liverpool in the 18th century. Further population growth came in the following century, resulting during the 1860s in a staged transfer of the High Courts, the Lieutenant Governor's residence (actually located in nearby Onchan), and finally the seat of the legislature, Tynwald, to Douglas from the ancient capital, Castletown. The city is the island's main hub for business, finance, legal services, shipping, transport, shopping, and entertainment. The annual Isle of Man TT motorcycle races start and finish in Douglas.

HMS Valkyrie was a shore establishment or "stone frigate" of the Royal Navy located in Douglas, Isle of Man. The establishment was split into two component parts, Valkyrie I and Valkyrie II.

Manx Radio (legally Radio Manx Ltd.) (Manx: Radio Vannin) is the national commercial radio station for the Isle of Man. It began broadcasting on 29 June 1964, almost ten years before legal commercial radio was licensed in the United Kingdom. The Isle of Man, having its own government and laws, was not subject to the rules prohibiting commercial broadcasting in the UK. However, the Manx Government still had to apply to the UK's General Post Office for a frequency and for permission to broadcast. First requested in 1960, a licence was eventually granted in May 1964. It was allocated an FM frequency of 89.0 MHz and a comparatively low power of 50 watts. In October 1964, an additional frequency of 1594 kHz AM was allocated to the station to provide greater coverage, although again at a limited power of 50 watts. It broadcasts primarily in English with several hours per week of Manx language programming. As of September 2023, the station broadcasts to a weekly audience of 26,000 listeners, according to RAJAR.
