IHS is a Christogram, an abbreviation of the name of Jesus Christ. IHS or IHC are the first three capital letters of the Greek name of Jesus, IHΣΟΥΣ (iota-eta-sigma), also sometimes written as ΙΗΣ. This is commonly used within the Western Christian churches. In the Eastern Churches, the Christogram ICXC is most widely used.
