Athaliah (; ; ; ) was queen consort of Judah as the wife of King Jehoram, a descendant of King David, and later queen regnant for six years.
William F. Albright has dated her reign to 842–837 BCE, while Edwin R. Thiele in the third edition of his magnum opus dates her reign from 842/841 to 836/835 BCE. However, a starting date of 842/841 for Athaliah is one year before the date of 841/840 that Thiele gave for the death of her son, Ahaziah, a conflict that Thiele never resolved. The present article accepts the one-year adjustment to Thiele's dates for Ahaziah given by later scholars that is explained in the Rehoboam and Ahaziah articles, thereby reconciling Thiele's dates for Athaliah with those of her predecessor. These dates are also compatible with cross-synchronisms between Ahaziah and Athaliah and the northern kingdom.
