The outer layer of the meninges is called the **dura mater**.

### Explanation

The meninges consist of three protective layers surrounding the brain and spinal cord. From the outermost to the innermost, these layers are:

1. **Dura Mater**: This is the tough and durable outer layer that provides the most protection. It is made of dense connective tissue and is closely associated with the inner surface of the skull.

2. **Arachnoid Mater**: This is the middle layer that resembles a spider web in appearance. It provides a cushioning effect and contains cerebrospinal fluid in the subarachnoid space.

3. **Pia Mater**: This is the innermost layer, which is thin and delicate. It closely adheres to the surface of the brain and spinal cord, following all their contours.

In conclusion, among the options given, the correct answer is **dura mater**.
