In [[mathematics]], and more particularly in [[number theory]], '''primorial''', denoted by "{{math|''p<sub>n</sub>''#}}", is a [[Function (mathematics)|function]] from [[natural number]]s to natural numbers similar to the [[factorial]] function, but rather than successively multiplying positive integers, the function only multiplies [[prime number]]s.

The name "primorial", coined by [[Harvey Dubner]], draws an analogy to ''primes'' similar to the way the name "factorial" relates to ''factors''.
