Ziva David (/ˈziːvə dəˈviːd/; Hebrew: זיוה דויד, Ziva: "Brilliance"; birth date November 12, 1982, Be'er Sheva in the Negev desert of southern Israel) is a fictional character from the NCIS television series by CBS Television, portrayed by Chilean-born American actress Coté de Pablo.

David was introduced in the Season 3 premiere episode, "Kill Ari (Part 1)", and became a regular cast member from the episode "Silver War". David replaced Caitlin "Kate" Todd (Sasha Alexander), who was killed at the hands of Ziva's half-brother, Ari Haswari (Rudolf Martin), in the Season 2 finale.

Ziva is introduced to the show as an Israeli citizen, agent of the Mossad, daughter of Mossad Director Eli David, and friend of NCIS Director Jenny Shepard. She was assigned to NCIS as a liaison officer in an arrangement between Eli and Jenny, a position she held for four years until she returned to Mossad in the Season 6 finale, "Aliyah". After being captured by terrorists in Somalia while on assignment for Mossad and presumed dead, she was eventually saved by Gibbs, Tony and McGee who brought her back to America to a reunion with Ducky and Abby.

Upon passing her citizenship exam, Ziva was sworn in as a U.S. citizen with McGee, Ducky, Abby and Palmer being present at her ceremony.

In the Season 9 premiere episode "Nature of the Beast", after being a Probie for nearly two or three years, Ziva finally earned her status as an NCIS Special Agent.
