The United States has about 3 million miles of natural gas pipeline when you include all the mainline, gathering, and distribution pipes that move gas from production fields all the way to homes and businesses.

What that number includes

  • The figure covers the entire natural gas pipeline network: long-distance transmission lines, regional mains, and local distribution lines to end users.
  • Federal energy data describe this as an ā€œabout 3 million milesā€ network, so it is inherently approximate rather than an exact, fixed total.

Why estimates vary

  • Some sources quote only interstate and intrastate transmission lines (around 300,000–360,000 miles), which excludes most local distribution piping.
  • Others, including official U.S. energy statistics, add gathering and distribution lines, which pushes the network length into the multi‑million‑mile range.

Recent context

  • Industry and government descriptions from the 2020s continue to reference ā€œabout 3 million milesā€ of natural gas pipelines in the U.S., indicating no drastic change from that scale in recent years.
  • Within that total, natural gas lines make up the vast majority of U.S. pipeline mileage; pipelines for oil, liquids, and COā‚‚ are much smaller in aggregate (on the order of a few hundred thousand miles).
