texlive – A comprehensive distribution of TeX and friends

A comprehensive TeX system that you can install on your hard disk. It includes support for most Unix system architectures, including GNU/Linux and MacOS, and for Windows. The MacTeX distribution is an unchanged TeX Live plus some Mac-specific software, but is distributed in a separate archive.

The TeX, PDF(e)TeX, XeTeX, LuaTeX, and other engines are provided in the distribution, with several different running formats each; a wide range of support programs and macro packages is also included.

Beware: the download from CTAN is large (several GB); it comes in the form of an ISO image, and is available from CTAN mirrors through the Sources link below.

Other ways to acquire TeX Live include network installation, tarballs, and mirroring.
