The Sacred Fraternity of the Cross is a Hermetic society founded by Alexander Guilford (known in the order as Frater Auriel) in London in the 1930s.

The order promoted Christian mysticism, and is most known for a variation on the Hermetic Order of the Golden Dawn's Supreme Invoking Ritual of the Pentagram (SIRP), which utilized scenes from the alchemical work Rosarium philosophus, and was reconfigured to allow use of the Pentagrammaton over the Tetragrammaton. It dissolved in the early 1960s after the unexpected death of the Dux Ducis, Simone Montbarde (known in the order as Frater Carpocrates).
