豆科植物约650属，18000种 ，广布于全世界。我国有172属，1485种，13亚种，153变种，16变型；各省区均有分布。本科植物的化石在白垩纪已有记录，是被子植物中仅次于菊科及兰科的三个最大的科之一。在分类方法上，亦有不少植物学家将本科分成3个独立的科，即含羞草科、云实科和蝶形花科。在此为中国植物志的分类。
豆科植物的花多呈两性，稀单性，辐射对称或两侧对称，通常排成总状花序、聚伞花序、穗状花序、头状花序或圆锥花序。其花的颜色丰富多彩，白、黄、淡黄、褐黄、粉红、红、紫、黄绿等等。有些在生长过程中颜色变化。
农业上的豆科作物有大豆、花生、蚕豆、豌豆、赤豆、绿豆、豇豆、四季豆和扁豆等，是人类食品中淀粉、蛋白质、油和蔬菜的重要来源之一。
除此之外，有些木材可供建筑、家具、农具；有些的枝干和树皮常含有单宁、树胶及染料，可用于医药、印染及其他工业；有的则是常见的绿化及观赏植物。
