4923 Clarke is an asteroid. It was discovered on March 2, 1981 by Schelte J. Bus who also discovered 5020 Asimov on the same day. It orbits within the main asteroid belt.†

The asteroid is named after the science fiction writer Arthur C. Clarke, author of 2001: A Space Odyssey. In the postscript to his novel 3001: The Final Odyssey, Clarke jokingly expresses disappointment that he did not receive asteroid 2001 as his namesake, instead it was named for Albert Einstein.
