Aluminium diboride (AlB₂) is a chemical compound made from the metal aluminium and the non-metal boron. It is one of two compounds of aluminium and boron, the other being AlB₁₂ that are both commonly referred to as aluminium boride.

Structurally the B atoms form graphite like sheets with Al atoms between them, and this is very similar to the structure of magnesium diboride. Single crystals of AlB₂ exhibit metallic conductivity along the axis parallel to the basal hexagonal plane.
