الشريان التاجي الأيسر (left coronary artery؛ LCA؛ ويـُعرف أيضاً بإسم الشريان التاجي الرئيسي الأيسر أو الشريان التاجي الجذعي الرئيسي الأيسر) هو الشريان التاجي النابع من الأورطى فوق left cusp of the aortic valve, and supplies blood to the left side of the heart muscle.^{[بحاجة لمصدر]} The left coronary artery typically runs for 10-25 mm, then bifurcates into the left anterior descending artery, and the left circumflex artery.^[1]

The part that is between the aorta and the bifurcation only is known as the left main artery (LM), while the term "LCA" might refer to just the left main, or to the left main and all its eventual branches.^{[بحاجة لمصدر]}

Sometimes, an additional artery arises at the bifurcation of the left main artery, forming a trifurcation; this extra artery is called the ramus or intermediate artery.^[2]

A "first septal branch" is sometimes described.^[3]
