Are there woman masons

No Freemasons are only for men; women do have their own "mason" group.

Correction:

There are Freemason organizations that include women, these lodges are referred to as Co-Masonic lodges. The biggest organization of Co-Masonry is Le Droit Humain.

They are not however, "recognized" by most "mainstream" Grand Lodges.

There are also all-female Masonic Lodges in Britain, but members of these cannot visit all-male lodgesand these lodges cannot be visited by male masons.
