Saint Sulien, Sulian, or Silin was the reputed 6th-century founder-abbot of a monastery at Luxulyan in Cornwall. His feast day is 29 July.
There have probably been other Christian Celtic saints with the same (or similar) name, and a variant of it is also used as an alias of Saint Tysilio (see below).
