Viking Link is a 1,400 MW HVDC submarine power cable between the United Kingdom and Denmark, which was completed in 2023.

[2] The cable has a total length of 765 kilometres (475 miles), of which 650 km (400 mi) is undersea, passing through Danish, German, Dutch and British waters.

In November 2015 Viking Link was put on the EU "Projects of Common Interest" list, along with the COBRAcable between Jutland and the Netherlands, and the Krieger offshore wind turbine cable to Germany.

[8] In reaction to the Brexit referendum Viking Link stated that the plans to build and operate the interconnector remain unchanged and that they consider the project unlikely to be influenced since it has a strong business case, while National Grid claims that leaving the internal energy market would jeopardize interconnector projects such as Viking Link.

[9] In July 2019 Viking Link announced three contracts totaling €1.1 billion, one with Siemens Energy for the two onshore substations and two for the manufacture and laying of the undersea cables to be done by Prysmian Powerlink S.r.l.

[17] In August 2023 the cable including its terminations, land and subsea joints completed final electric testing at 735 kV, i.e. 40% above its nominal operating voltage.

[22][20] From 14 January 2024 the Danish transmission system operator Energinet implemented changes that allow Viking Link to transmit at its full capacity under certain circumstances.

[28] By the first quarter of 2024 Viking Link had earned ca 20 million Euro, to be evenly split between National Grid plc and Energinet.
