Getlink, formerly Groupe Eurotunnel, is a European public company based in Paris that manages and operates the infrastructure of the Channel Tunnel between England and France, operates the Eurotunnel Shuttle train service, and earns revenue on other trains that operate through the tunnel (Eurostar passenger and DB Schenker freight).

Groupe Eurotunnel was established on 13 August 1986 to finance, build, and operate the Channel Tunnel under a concession granted by the French and British governments. The tunnel was constructed between 1988 and 1994 by TransManche Link (TML) under a contract issued by Groupe Eurotunnel; construction costs would overrun considerably, from TML's original estimate of £4.7 billion to the final cost of £9.5 billion. On 6 May 1994, the completed tunnel was officially opened. Its rail infrastructure comprises 50.45 kilometres (31.35 miles) of double track railway in the main tunnels, plus extensive surface-level terminal facilities at Folkestone in England and Calais in France. The rail network for operation of the Eurotunnel Shuttle train services is entirely self-contained, with connections near the two terminals to the respective national railway networks. Signalling and electric traction supply are also under Getlink control.

In 1995, a loss of £925 million was reported by Groupe Eurotunnel; this was partly due to many of the planned services to use the tunnel not yet being permitted. On 2 August 2006, following failed debt restructuring plans, Groupe Eurotunnel was placed into bankruptcy protection; a restructuring plan that involved a £2.8 billion funding arrangement and a debt-for-equity swap was approved by shareholders in May 2007. That same year, it reported a net profit of €1 million, the company's first profitable year. In December 2009, Groupe Eurotunnel and SNCF acquired the French rail freight operator Veolia Cargo, gaining multiple subsidiaries in the process. In June 2010, the company acquired British rail freight company First GBRf for £31 million from FirstGroup. In 2012, Groupe Eurotunnel acquired three Channel ferries formerly belonging to the liquidated SeaFrance ferry service, establishing MyFerryLink to operate them, although this was discontinued due to monopoly allegations after a brief period. On 20 November 2017, Groupe Eurotunnel changed its name to Getlink. In March 2018, the Italian holding company Atlantia acquired the 15.49% stake of Goldman Sachs in Getlink, for roughly €1 billion.
