is the US Fortran standards committee, known formally as PL22.3, a technical subcommittee of the InterNational Committee for Information Technology Standards (INCITS) formerly known as the National Committee for Information Technology Standards (NCITS).

J3 developed the Fortran 66, Fortran 77, Fortran 90, Fortran 95, Fortran 2003, and Fortran 2008 standards. Fortran 2008 is an upwardly-compatible extension of Fortran 2003, adding, among other things, more expression of parallel computation (via coarrays and the do-concurrent construct), improved facilities for data organization (via enhancements to modules), and an enlarged intrinsic library (with more mathematical and bit-manipulating procedures).

J3 is currently working under WG5 direction to produce a new revision of the Fortran standard, tentatively called Fortran 15. This will be a minor revision of Fortran 2008. The work plan and schedule are available.

J3 meetings, documents, and membership are open to anyone worldwide. Meeting information and documents are available from this website; membership information may be obtained from any committee member. Any interested party can submit a paper for consideration at a J3 meeting by following the J3 committee guidelines.
