Countries by gas pipeline length

Showing the top 50. A cross-border pipeline is counted at full length for every country it crosses, so these figures sum to more than the network's total length. Browse every country in the directory.

Which country has the most gas pipeline?

United States, with 427,382 km across 516 tracked pipelines.

Why might these figures not add up to the total network length?

Because a pipeline that crosses two or more countries is counted at its full length in each one it crosses, the same convention this site's own country pages use. This ranking measures network present in a country, not a share of one continuous route.

Does this include pipelines that are proposed or under construction?

Yes — length is a property of a route rather than a statement about capacity, so this ranking, like the length ranking it is grouped from, does not carry the never-add-statuses-together rule that capacity does.

How is a pipeline's length measured?

GEM's reported figure where given, and the length measured from the mapped route where none is reported. A pipeline with neither is excluded.
