苹果酸脱氢酶 (草酰乙酸脱羧) (NADP⁺)（英語：malate dehydrogenase (oxaloacetate-decarboxylating) (NADP⁺)，EC 1.1.1.40 （页面存档备份，存于互联网档案馆））是一种以NAD⁺或NADP⁺为受体、作用于供体CH-OH基团上的氧化还原酶。这种酶能催化以下酶促反应：

(S)-苹果酸 + NADP⁺ $\rightleftharpoons$ 丙酮酸 + CO₂ + NADPH

苹果酸脱氢酶 (草酰乙酸脱羧) (NADP⁺)是C₄和CAM植物固定二氧化碳过程中使用的三种脱羧酶之一（其余两种分别为苹果酸脱氢酶 (脱羧)和磷酸烯醇丙酮酸羧化激酶）。
