The GROSSE LANDESLOGE DER FREIMAURER VON DEUTSCHLAND (GLL FvD or GLL), also known as the Freimaurerorden (FO), is a union of regular Masonic lodges founded in 1770 by Johann Wilhelm Kellner von Zinnendorf, the then General Medical Officer of the Prussian Army. It is one of the United Grand Lodges of Germany (VGLvD) and is among the three so-called Old Prussian Grand Lodges.

Unique to the GLL FvD is its Christian character; it names Jesus Christ as its Grand Master, distinguishing it in content and organization from other Masonic teachings. Although it is not a religious order in the traditional sense and does not intend to be, it requires its members to profess the teachings of Jesus Christ as contained in the Holy Scriptures. Membership of a specific Christian denomination is not necessary.
