白海豚属（学名：Sotalia）也称侏儒白海豚属，是鲸目海豚科的一属，分布于南美洲，现存2种：

• 亚马逊白海豚（Sotalia fluviatilis）
• 圭亚那白海豚（Sotalia guianensis）

The dolphin genus Sotalia is considered to have two member species with the classification of Sotalia guianensis as a distinct species from Sotalia fluviatilis in 2007. This was a result of recent morphometric analyses, as well as mitochondrial DNA analysis.
