What is the former name of mountain range where Capitol located in Hunger Games?

The mountain range where the Capitol is located in The Hunger Games is called the Capitol Mountains. It's not a former name; it's the only name we know for the range in the books and movies.

It's important to note that the Capitol Mountains are not explicitly named in the books. However, they are referred to as "the mountains" or "the Capitol's mountains" in the narration, and their existence is evident from descriptions of the landscape and geography of Panem.

In the film adaptations, the Capitol Mountains are shown more prominently and often referred to directly, solidifying their name as "Capitol Mountains" in the fandom.
