基尔霍夫电路定律（Kirchhoff Circuit Laws）简称为基尔霍夫定律，指的是两条电路学定律，基尔霍夫电流定律与基尔霍夫电压定律。它们涉及了电荷的守恒及电势的保守性。1845年，古斯塔夫·基尔霍夫首先提出基尔霍夫电路定律。现在，这定律被广泛地应用于电机工程学。

从马克士威方程组可以推导出基尔霍夫电路定律。但是，基尔霍夫并不是依循这条思路发展，而是从格奥尔格·欧姆的工作成果加以推广得之。

Kirchhoff's circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of Maxwell. Widely used in electrical engineering, they are also called Kirchhoff's rules or simply Kirchhoff's laws.
