精确制导武器（Precision-guided weapon）是指具有导引系统，能够在发射后进行控制，以提供命中率与精确度的各种武器。这种设计使武器能具有最大限度的直接杀伤力，并可减少弹药的消耗量及平民伤亡。鼻祖是德国的弗里茨 X。

在这一项分类下的武器包括各种飞弹，有导引能力的炸弹，炮弹，火箭，无人机等等。

A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, and to minimize collateral damage.

Because the damage effects of explosive weapons decrease with distance due to an inverse cube law, even modest improvements in accuracy (hence reduction in miss distance) enable a target to be attacked with fewer or smaller bombs. Thus, even if some guided bombs miss, fewer air crews are put at risk and the harm to civilians and the amount of collateral damage may be reduced.
