Clement C. Moore (1779–1863) was a professor of Oriental and Greek literature at Columbia College (now Columbia University) in New York.

The poem 'Twas the Night Before Christmas' was first published anonymously in 1823 but was later attributed to Moore and was included in an 1844 anthology of his works.

Moore's former land in New York is noted today by Clement Clarke Moore Park where local residents often gather on the last Sunday before Advent for a reading of his most famous poem.
