Downhill Railway Tunnels near Castlerock on the NIR network.

Template:GeoGroup This is a list of road, railway, waterway, and other tunnels in the United Kingdom.

A tunnel is an underground passageway with no defined minimum length, though it may be considered to be at least twice as long as wide. Some government bodies define a tunnel as Template:Convert in length or longer.<ref>Template:Cite web</ref>

A tunnel may be for pedestrians or cyclists, for general road traffic, for motor vehicles only, for rail traffic, or for a canal. Some are aqueducts, constructed purely for carrying water—for consumption, for hydroelectric purposes or as sewers—while others carry other services such as telecommunications cables. There are even tunnels designed as wildlife crossings for European badgers and other endangered species.

The longest tunnel in the United Kingdom is the Northern line at Template:Convert. This will be superseded in the 2030s by the Template:Convert Woodsmith Mine Tunnel in North Yorkshire that will transport polyhalite from North Yorkshire to a port on Teesside.<ref>Template:Cite news</ref><ref>Template:Cite news</ref> Standedge Tunnel at Template:Convert is the longest canal tunnel in the United Kingdom. When completed in the late 2020s, the Chiltern tunnel will be the 2nd longest mainline railway tunnel in the UK at Template:Convert.<ref name=":02">Template:Cite web</ref>
