'''奎尼酸脱氢酶'''（{{lang-en|quinate dehydrogenase}}，[[EC编号|EC]] [http://enzyme.expasy.org/EC/1.1.1.24 1.1.1.24] {{Wayback|url=http://enzyme.expasy.org/EC/1.1.1.24 |date=20200925144235 }}）是一种以[[烟酰胺腺嘌呤二核苷酸|NAD<sup>+</sup>]]或[[烟酰胺腺嘌呤二核苷酸磷酸|NADP<sup>+</sup>]]为[[受体 (生物化学)|受体]]、作用于[[供体]][[次甲基|CH]]-[[羟基|OH]][[基团]]上的[[氧化还原酶]]。这种[[酶]]能[[催化]]以下[[酶促反应]]：

:[[奎尼酸|L-奎尼酸]] + [[烟酰胺腺嘌呤二核苷酸|NAD<sup>+</sup>]] <math>\rightleftharpoons</math> [[3-脱氢奎尼酸]] + NADH + [[氢离子|H<sup>+</sup>]]

上述反应中的NAD<sup>+</sup>不能以NADP<sup>+</sup>替代。奎尼酸脱氢酶以[[奎尼酸]]为特异性[[底物]]，而[[苯丙酮酸]]、[[苯丙氨酸]]、[[肉桂酸]]和[[莽草酸]]则不能作为底物。这种酶主要参与苯丙氨酸、[[酪氨酸]]和[[色氨酸]]的[[生物合成]]过程。
