心磷脂（英语：Cardiolipin），一种磷脂，亦称双磷脂酰甘油。是潘伯恩1941年从新鲜的牛心肌中分离出来的，心磷脂广泛存在于植物、微生物、高等动物界。心磷脂主要存在于动物细胞中线粒体的内膜，15%的磷脂存在心肌。

Cardiolipin (IUPAC name "1,3-bis(sn-3’-phosphatidyl)-sn-glycerol") is an important component of the inner mitochondrial membrane, where it constitutes about 20% of the total lipid composition. It can also be found in the membranes of most bacteria. The name ‘cardiolipin’ is derived from the fact that it was first found in animal hearts. It was first isolated from beef heart in the early 1940s. In mammalian cells, but also in plant cells, cardiolipin (CL) is found almost exclusively in the inner mitochondrial membrane where it is essential for the optimal function of numerous enzymes that are involved in mitochondrial energy metabolism.
