'''黄酮醇合酶'''（{{lang-en|flavonol synthase}}；{{EC number|1.14.11.23}}）在酶学中在[[酶学]]中是一个[[催化]]如下[[化学反应]]的酶。

: 黄烷酮醇 + α-酮戊二酸 + O<sub>2</sub> <math>\rightleftharpoons</math> 黄酮醇 + 琥珀酸 + CO<sub>2</sub> + H<sub>2</sub>O

此酶的三种[[底物]]分别是[[黄烷酮醇]]、[[α-酮戊二酸]]与[[氧气]]，而它的四种[[产物 (化学)|产物]]则分别是[[黄酮醇]]、[[琥珀酸]]、[[二氧化碳]]与[[水]]。

此酶属于[[氧化还原酶]]家族，特异性地作用于配对的供体，并以氧气作为氧化剂结合或还原氧气。被结合的氧无需借由α-酮戊二酸作为一个供体或是被脱氢的方式被传递。此酶类的系统命名为'''黄烷酮醇，2-酮戊二酸：氧氧化还原酶'''。此酶参与[[黄酮类化合物生物合成]]。
