The anchored cross, or mariner's cross, is a stylized cross in the shape of an anchor. It is a symbol which is shaped like a plus sign depicted with anchor-like fluke protrusions at its base. There are many variations on this symbol, but the most common form connects a ring with a bar, with a cross-bar, terminating on the other end with two curved branches or arrowheads. The anchor symbolizes hope, steadfastness, calm and composure. It also can symbolize security in one or more uncertain experiences of life, such as sea voyages, one's fate after death, and the vagaries of fortune.

An anchor is a device, normally made of metal, used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα.
