Zeruiah (/zəˈruːjə/ צרויה sometimes transliterated Tzruya or Zeruya) was a sister of King David.
According to both the Hebrew Bible and the Babylonian Talmud, Zeruiah was a daughter of Jesse and sister of Abigail, to whom reference is made in 1 Chronicles (1 Chronicles 2:13–17) and 2 Samuel (2 Samuel 17:25).
However, her sons are invariably mentioned with the matronymic "son of Zeruiah", in marked contrast to most other Biblical characters (and people in many other cultures) who are known by a patronymic.
This suggests that she was an exceptionally important person, though the specific circumstances are not given.
Her name is used, though not very frequently, as a female given name in modern Israel (see Tzruya Lahav, Zeruya Shalev).
