List of Chapter Masters - Chapter Masters are the leaders of Space Marine Chapters.
| Name | Chapter | Notes | Sources |
| Castellan Zargo | Angels Encarmine | This Chapter Master is one of the most active within the Adeptus Astartes. He cannot rest at peace and so forever seeks opportunities to lead his Battle-Brothers on campaign. As a result, the Angels Encarmine are rarely at full strength, though what they lack in numbers is more than compensated for in determined fervour. | Codex: Blood Angels (5th Edition) pg. 54 |

| Artor Amhrad | Astral Knights | When fifteen Space Marine task forces failed to stop a large Necron World Engine,the Master of the Astral Knights Chapter, adopted a desperate strategy. Forgoing weaponry that had many times proved to be ineffective, Amhrad employed the Astral Knights' Battle Barge itself against the World Engine's shields. The moment the Battle Barge pierced the shields, the Astral Knights had taken to their Drop Pods. For 100 hours and more the Astral Knights wrought havoc against a superior force of tens of thousands of Necron warriors. Reduced in size to the Chapter Master, and five brave Battle-Brothers only then did they succeed in their quest. Amhrad detonated melta-charges that destroyed a vast Necron tomb complex that housed many of the World Engine's command arrays which brought down the vessel's void shields. This allowed the Imperial Navy's starships to destroy the World Engine with cyclonic torpedoes. On the outskirts of the Danorra System lies the scarred and lifeless planet of Safehold. It is here, in the dead heart of the Battle Barge Tempestus, that a shrine was raised in their memory. Seven-hundred and seventy-two arbalstone statues stand silent vigil amongst the ruined flagship, one for each fallen Battle-Brother of the Astral Knights. | Codex: Space Marines (5th Edition)pp. 44-45 |
