**黃酮合酶**（英語：flavone synthase；EC 1.14.11.22）在酶學中在酶學中是一個催化如下化學反應的酶。

　
: 黃烷酮 + α- 酮戊二酸 + O2 $\rightleftharpoons $ 黃酮 + 琥珀酸 + CO2 + H2O

此酶的三種底物分別是黃烷酮、α- 酮戊二酸與氧氣，而它的四種產物則分別是黃酮、琥珀酸、二氧化碳與水。

此酶屬於氧化還原酶家族，特異性地作用於配對的供體，並以氧氣作為氧化劑結合或還原氧氣。被結合的氧無需藉由 α- 酮戊二酸作為一個供體或是被脫氫的方式被傳遞。此酶類的系統命名為**黃烷酮，2 - 酮戊二酸：氧氧化還原酶（脫水）** 。此酶參與黃酮類化合物生物合成與異黃酮類化合物生物合成。
