What is a male alpha wolf called?

There isn't a specific term for a male alpha wolf.

While "alpha male" is a commonly used term, it's important to note that the concept of a strict "alpha" hierarchy in wolf packs is now considered outdated by scientists.

Modern research indicates that wolf pack dynamics are more complex and fluid than previously believed. While there are usually dominant individuals within a pack, their roles and relationships are constantly shifting based on factors like age, health, and social connections.

So, instead of "alpha male," you could simply refer to the dominant male wolf in a pack as the "dominant male" or "leader".
