太阳鱼属（Lepomis）是一个淡水鱼属，隶属于太阳鱼科。

S旗下的一些种类最大可长至41厘米（16英寸），不过平均长度只有10～20厘米（3.9～7.9英寸）。广泛分布于美国和加拿大的河流中，其中一些种更被运输到世界各地，甚至成为了入侵物种，其中一些种的贸易行为就已在德国被明令禁止。常被钓鱼者当做一种“panfish”。

该属有时也被划分在鲤科下，但这只是因为与该科下欧鳊属（Abramis）的异名混淆了。Lepomis 一词来自于希腊语 λεπίς （鳞）和πώμα （鳃盖）。

太阳鱼属是太阳鱼科第一个已知的属，其化石记录可追溯到1360万年前的中新世中期。

Lepomis is a genus of freshwater fish in the sunfish family, Centrarchidae, in the order Perciformes. Perhaps the most recognizable species of this genus is the bluegill.

Some Lepomis species can grow to a maximum overall length of 41 cm (16 in), though most average around 10–20 cm (3.9–7.9 in). They are widely distributed throughout the lakes and rivers of the United States and Canada, and several species have been transplanted and flourished around the world, even becoming pests. Trade in some Lepomis species is prohibited in Germany for this reason. Many are sought by anglers as panfish, and large numbers are bred to stock lakes, rivers, and tributaries.
