The lysophosphatidic acid receptors (LPARs) are a group of G protein-coupled receptors for lysophosphatidic acid (LPA) that include:

• Lysophosphatidic acid receptor 1 (LPAR1; formerly known as EDG2, GPR26)
• Lysophosphatidic acid receptor 2 (LPAR2; formerly known as EDG4)
• Lysophosphatidic acid receptor 3 (LPAR3; formerly known as EDG7)
• Lysophosphatidic acid receptor 4 (LPAR4; formerly known as GPR23, P2RY9)
• Lysophosphatidic acid receptor 5 (LPAR5; formerly known as GPR92)
• Lysophosphatidic acid receptor 6 (LPAR6; formerly known as GPR87, P2RY5)
