A clade is a group of organisms that includes a common ancestor and all of its descendants, shown as branches on a tree diagram. Scientists use clades to understand evolutionary relationships because they reveal which species are most closely related by shared ancestry.

演化支（英語：clade，拉丁語：cladus）又稱支序群、分支群，是一個生物分類學的類別，包含著單一的共同祖先及其所有後裔。亦即：系統發生樹中一條完整的分支（包含了分岔出來的點、再分岔出去的次分支、及其下更小分支）稱為一條演化支；可簡單想成一個「類群」，所以又稱為 支序群、分支群。而演化分支的序列，或親緣分支順序，就稱作支序。其英語語源來自古希臘文 κλάδος (kládos)，意為“分枝”。 任何一個演化支都可以說是一個單系群，並以種系發生學的樹狀圖或支序分類學的演化樹來表示。
