蝲蛄科（學名：Cambaridae）是十足目下的一個科，亦是淡水龙虾三個科之中最大的一個，包含有超過400個物種。属该科物种体型略似龙虾而较小，在部分地区被称为小龙虾。头胸部较长，呈长卵圆形。前三对步足都有螯，第一对特别发达。大部份分布于北美洲大分水嶺以東，少部份分布於東亞、日本等地。栖息山溪和附近河川中。是肺吸虫中间宿主，捕食时要注意，不能生食。 根據一項2006年發表的分子研究，蝲蛄科很大可能是一個並系群，包含了雕蝦科（Astacidae）整個科，而Cambaroides的地位仍然未定。

The Cambaridae are the largest of the four families of freshwater crayfish, with over 400 species. Most of the species in the family are native to the United States east of the Great Divide and Mexico, but fewer range north to Canada, and south to Guatemala and Honduras. Three live on the island of Cuba. The species in the genus Cambaroides are only found outside North America, as they are restricted to eastern Asia.
A few species, including the invasive Procambarus clarkii and Faxonius rusticus, have been introduced to regions far outside their native range (both in North America and other continents). Conversely, many species have tiny ranges and are seriously threatened; a few are already extinct.
