Ida is a mountain range in Asia Minor, extending from Phrygia through Mysia into the Troad. The city of Troy was situated at its base. Ida is the scene of many ancient Greek legends. The southern part of the range was called Gargarus, the highest peak of which is 5,749 feet above the sea. Here there was a temple of Cybele, who therefore was called the Idaean Mother. From Ida flow several famous streams, such as the Granicus, Simois, and Scamander.

There is another Ida (8,055 feet) in Crete, extending from west to east, now called Psiloriti. Here Zeus was said to have been educated.
