David Mark Weber (born October 24, 1952) is an American science fiction and fantasy author. He was born in Cleveland, Ohio. Weber and his wife Sharon live in Greenville, South Carolina with their three children and "a passel of dogs".

Previously the owner of a small advertising and public relations agency, Weber now writes science fiction full time.

His novels range from epic fantasy (Oath of Swords, The War God's Own) to space opera (Path of the Fury, The Armageddon Inheritance) to alternate history (1632 series with Eric Flint) to military science fiction with in-depth characterization.

Many of his stories have military—particularly naval—themes. By frequently placing female leading characters in what have previously been seen as traditionally male roles, he has explored the challenges faced by women in the military and politics. In his writing, he creates a consistent and rationally explained technology and society.

The most popular character he has created is Honor Harrington. Her story, together with the "Honorverse" she inhabits, has been developed through a series of 13 novels, four shared-universe anthologies, and two sub-series. The series has over 3 million copies in print, and more than thirteen of Weber's titles have appeared on the New York Times Best Seller list.

David (Hebrew: דָּוִד, דָּוִיד, Modern David Tiberian Dāwîḏ; ISO 259-3 Dawid; Strong's Daveed; beloved; Arabic: داوود‎ or داود‎ Dāwūd) was, according to the Hebrew Bible, the second king of the United Kingdom of Israel and, according to the Gospel of Matthew and the Gospel of Luke, an ancestor of Jesus. David is seen as a major Prophet in Islamic traditions. His life is conventionally dated to c. 1040–970 BC, his reign over Judah c. 1010–1003 BC,^{[citation needed]} and his reign over the United Kingdom of Israel c. 1003–970 BC.^{[citation needed]} The Books of Samuel, 1 Kings, and 1 Chronicles are the only sources of information on David, although the Tel Dan stele records "House of David", which some take as confirmation of the existence in the mid-9th century BC of a Judean royal dynasty called the "House of David".

David is very important to Jewish, Christian and Islamic doctrine and culture. In Judaism, David, or David HaMelekh, is the King of Israel, and the Jewish people. Jewish tradition maintains that a direct descendant of David will be the Messiah. In Islam, he is known as Dawud, considered to be a prophet and the king of a nation. He is depicted as a righteous king, though not without faults, as well as an acclaimed warrior, musician, and poet, traditionally credited for composing many of the psalms contained in the Book of Psalms.
