The CAMP test is a test to identify Group B β-streptococci based on their formation of a substance (CAMP factor) that enlarges the area of hemolysis formed by β-hemolysin from Staphylococcus aureus. It is frequently used to identify Listeria spp.

Although usually used to identify group "B", there is some evidence that the CAMP factor gene is present in several groups of streptococci, including group "A".
A similar factor has been identified in Bartonella henselae.
It is an acronym for "Christie Atkins Munch-Petersen", for the three researchers who discovered the phenomenon.
It is often incorrectly reported as the product of four people (counting Munch-Petersen as two people).
The name has no relationship to Cyclic adenosine monophosphate (cAMP).
