Globally, Siphon (Sipho 
, Sifon 
, ศรีพร 
) is a common predominantly boy's, but very infrequently girly forename. The first name Siphon is characteristic of Sub-Saharan Africa, particularly South Africa, where it is a common boy's name, Botswana, where it is quite a rare epicene name, and Zimbabwe. Not in comparison with a country's population, the name is most common in South Africa, Nigeria, and Thailand. Very seldom, Siphon is the last name as well as the forename.
