Acastocephala is a genus of trilobites from the middle Silurian, known from the United Kingdom.
The name is derived from the genus Acaste and the Ancient Greek κεφαλή (kephalē) "head", indicating the headshield is similar to Acaste.
Acastocephala may contain the ancestor of Acastava.
- Acastocephala macrops occurs in the Middle Silurian of the United Kingdom (Wenlock Shale, Malvern, Worcestershire; Wenlock Limestone, Pen-y-Lan, Cardiff, and Dudley and Ludlow, Ledbury, Hereford).
- Acastocephala dudleyensis has been found in the Middle Silurian of the United Kingdom (Wenlock Limestone, Wren's Nest, Dudley, Worcestershire).
