In geometry, the **hexaoctagonal tiling** is a uniform tiling of the hyperbolic plane.

There are four uniform constructions of this tiling, three of them as constructed by mirror removal from the [8,6] kaleidoscope. Removing the mirror between the order 2 and 4 points, [8,6,1^{+}], gives [(8,8,3)], (*883). Removing the mirror between the order 2 and 8 points, [1^{+},8,6], gives [(4,6,6)], (*664). Removing two mirrors as [8,1^{+},6,1^{+}], leaves remaining mirrors (*4343).

The dual tiling has face configuration V6.8.6.8, and represents the fundamental domains of a quadrilateral kaleidoscope, orbifold (*4343), shown here. Adding a 2-fold gyration point at the center of each rhombi defines a (2*43) orbifold. These are subsymmetries of [8,6].
