达尔文雀（英语：Darwin's finches）或加拉巴哥雀是多种近缘的雀鸟物种，由查尔斯·达尔文所发现，当中有约13种在加拉巴哥群岛生活，另有一种在科科斯群岛。

达尔文在小猎犬号往南美的旅程对他推导出天择演化理论有贡献，故经常有人认为这些物种对达尔文推论演化论的过程有其贡献，但这不是事实：当遇到这些雀时达尔文认为他们不是近缘物种，事实上他认为这些根本不是雀(finches)。之后格兰特夫妇深入的研究并纪录在这些雀身上的演化变化。自1973年起，这对夫妇花了许多年追踪跨数代的数千个个体，结果呈现出个别物种对环境变化的反应。《雀喙之谜》是对于格兰特夫妇研究成果的讨论报导的一本书。

Darwin's finches (also known as the Galápagos finches) are a group of about fifteen species of passerine birds. They are often classified as the subfamily Geospizinae or tribe Geospizini. They belong to the tanager family and are not closely related to the true finches. The most closely known relative of the Galápagos finches is T. obscura. They were first collected by Charles Darwin on the Galápagos Islands during the second voyage of the Beagle. Apart from the Cocos finch, which is from Cocos Island, the others are found only on the Galápagos Islands.
