Girish (also spelled as Gireesh) is a Hindu name which means "lord of the Mountains" in Sanskrit ("giri" means Mountain and "ish" means God). This is a name of Lord Shiva, given because of his abode in the Himalayan Mountains. Lord Sri Ventakeshwara who resides on top of seven hills called Saptagiri also has Girish as one of his names.
Girish, the king of mountains, is also referred by some to Himavan, father of Shiva's wife Parvati.
Girish is used as a male name in India.
