Siege range is an attribute in Age of Empires III. It is the range at which a unit can throw siege (anti-building) projectiles. The amount of points the unit has determines how far the unit can destroy the building.

Most non-artillery and non-Ship units have a siege range of 6, exceptions to this include are the Abus Gun, the Arrow Knight, the Grenadier, the Arsonist and the Flamethrower, which have higher range.

The unit with the longest siege range is the Fixed Gun, with a range of 100. The next unit with the highest siege range is the mortar.
