Origin: Persian شاهين
Meaning: royal king
The name is composed of the Persian elements, shah (king) and in (royal). In Persian it is used to refer to a type of falcon, known in English as the Shaheen falcon also known as the peregrine falcon. An interesting and alternative bird-name, indeed!
As of 2009, its franconized form of Chahine was the 451st most popular male name. A Turkish form is Şahin.
