支尔格大会（普什图语：لويه جرګه），是阿富汗的一种传统部族首领大会，据考证已有1000多年历史。

早期的支尔格大会是普什图族的内部会议，但其后逐渐演变为阿富汗各部族均可参加的大会。支尔格大会没有规定的期限，一般直到各方达成共识后方得以散会。最近的一次支尔格大会召开于2003年12月14日，502位代表在喀布尔就草拟阿富汗的新宪法进行了20天的商议，最终于2004年1月4日散会。

A loya jirga (Pashto:لويه جرګه‎, "grand assembly") is a special type of jirga that is mainly organized for choosing a new head of state in case of sudden death, adopting a new constitution, or to settle national or regional issue such as war. It predates modern-day written or fixed-laws and is mostly favored by the Pashtun people but to a lesser extent by other nearby groups that have been influenced by Pashtuns (historically known as Afghans).
