Around the world, Ousainou (Ousainou 
) is a rare male forename. The forename Ousainou is habitual in Gambia, where it is quite a common male name, the United Kingdom, where it is a very rare boy's name, and the United States, where it is an extremely rare principally masculine, but very infrequently feminine name. Much less frequently, Ousainou is the last name as well as the forename.
