奇异果蛋白酶（EC 3.4.22.14；英语：Actinidain, Actinidia anionic protease, proteinase A2 of Actinidia chinensis）是一种在水果中发现的半胱氨酸蛋白酶，包括奇异果、凤梨、芒果、香蕉和木瓜都含有这种酵素。这种酶是木瓜蛋白酶样肽酶C1家族的一部分。^[1]^[2]^[3]^[4]

作为奇异果中已知的过敏原^[5]，该酶正在初步研究其对肠上皮细胞紧密连接蛋白的影响。^[6]^[7]

奇异果蛋白酶在商业上可用作嫩肉剂^[8]^[9]和用于乳制品的凝乳剂^[10]。奇异果蛋白酶的变性温度为60°C，低于类似的嫩肉酶凤梨蛋白酶和木瓜蛋白酶的变性温度。^[11]
