思维规律（英语：Law of thought），又称思考规律，是逻辑的公理基础。伯特兰·罗素在他的著作《哲学问题》中确立了三个思维规律:

一般而言在欧陆理性主义的方法中，它们被明确的假定并且是毋庸质疑的公理。

它们都归功于亚里士多德，并遭受了众多非议和分析(分别关于决定论和外延性)。在一定意义上，这标志了在十九世纪特别是Frege(他受到这些公式的巨大影响)之后在逻辑学中发生的事情。这种规律被假定为是基本的，有教育学价值的，而不是挑战于智力。这种态度只在二十世纪早期被放弃过一段时间，这可以在伯特兰·罗素 1911 年的著作中(在那里指出了它们三个)对它们的暗示中看出来。

The laws of thought are fundamental axiomatic rules upon which rational discourse itself is often considered to be based. The formulation and clarification of such rules have a long tradition in the history of philosophy and logic. Generally they are taken as laws that guide and underlie everyone's thinking, thoughts, expressions, discussions, etc. However such classical ideas are often questioned or rejected in more recent developments, such as Intuitionistic logic and Fuzzy Logic.
