X-shaped cross

A saltire, also called Saint Andrew's Cross, is a heraldic symbol in the form of a diagonal cross, like the shape of the letter X in Roman type. The word comes from the Middle French sautoir ("stirrup"), possibly owing to the shape of the triangular areas in the design.

It appears in numerous flags, including those of Scotland and Jamaica, and other coats of arms and seals. A variant, also appearing on many past and present flags and symbols, is the Cross of Burgundy.

A warning sign in the shape of a saltire is also used to indicate the point at which a railway line intersects a road at a level crossing.

In Unicode, the cross is encoded at U+2613 ☓ saltire (HTML ☓). See X mark for similar symbols that might be more accessible.

The saltire is one of the classic "honourable" ordinaries, geometric charges that span throughout (from edge to edge of) the shield.

When two or more saltires appear, they are usually blazoned as couped (cut off). For example, contrast the single saltire in the arms granted to G. M. W. Anderson—with the three saltires couped in the coat of Kemble Greenwood.

Diminutive forms include the fillet saltire, usually considered half or less the width of the saltire, and the saltorel, a narrow or couped saltire.

A field (party) per saltire is divided into four areas by a saltire-shaped "cut". If two tinctures are specified, the first refers to the areas above (in chief) and below (in base) the crossing, and the second refers to the ones on either side (in the flanks). Otherwise, each of the four divisions may be blazoned separately.
