雀科，学名Fringillidae，是鸟纲雀形目中的一个科。通常所说的雀类就是指这一科中的鸟。

雀科的鸟体形较小，外形似麻雀。锥状喙厚实有力，嘴峰隆起，上下嘴边缘平滑，闭合性好，这一点与鹀科的鸟有着明显的区别。本科中交嘴雀属的鸟喙的形态特殊。在解剖学上，角质腭两侧的纵棱平行，这是与文鸟科的重要区别点。尾羽12枚，初级飞羽10枚，但通常外侧的第一枚退化。

The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions.
