Elwin Ransom is the prominent character from C. S. Lewis's Space Trilogy series. He is the main character in the books Out of the Silent Planet and Perelandra, which are told almost entirely from his point of view. He is also a major character in the third book, That Hideous Strength, in which he plays a director of an organization resisting the demonic take-over of the world, though his role is that of mentor in the book, with the main characters arguably being Mark and Jane Studdock.
