In abstract algebra, the triple product property is an identity satisfied in some groups.

Let be a non-trivial group. Three nonempty subsets are said to have the triple product property in if for all elements , , it is the case that

where is the identity of .

It plays a role in research of fast matrix multiplication algorithms.
