Short answer: No. Tim Cook was baptized in a Baptist church as a child, a fact he stated in his own words in a 2015 Washington Post op-ed, and no reputable source documents Jewish parentage or ancestry on either side of his family. The Jewish Telegraphic Agency, reporting on his 2018 address to the Anti-Defamation League, described him plainly as "not Jewish."
What the record actually shows
- Born November 1, 1960, in Mobile, Alabama, and raised in Robertsdale. His father, Donald Cook, worked in a shipyard and his mother, Geraldine, worked at a pharmacy. He was salutatorian of Robertsdale High School in 1978, earned a BS in industrial engineering from Auburn University in 1982, and a Duke MBA in 1988 (background summary).
- March 29, 2015: writing in a Washington Post op-ed opposing Indiana's Religious Freedom Restoration Act, Cook described his own religious upbringing: "As a child, I was baptized in a Baptist church, and faith has always been an important part of my life. I was never taught, nor do I believe, that religion should be used as an excuse to discriminate" (a Washington Post op-ed of March 29, 2015, covered by CBS News).
- December 3, 2018: JTA, covering his ADL speech, wrote that "Cook, who is not Jewish, said in his address that the biblical mandate moves Apple to speak out on behalf of the rights of targeted groups" (JTA).
- December 3, 2018: at the ADL's "Never Is Now" summit in New York, Cook received the organization's first Courage Against Hate Award, per the ADL's own announcement. He quoted Leviticus in Hebrew: "Lo ta'amod al dam re'eikha." Do not be indifferent to the bloodshed of your fellow man (Times of Israel, Jerusalem Post).
- No documented Jewish ancestry, conversion, or Jewish practice appears in any reputable source. There is no disputed claim here to weigh.
- April 20, 2026: Apple announced that Cook will become Executive Chairman and that John Ternus will become CEO effective September 1, 2026, with Arthur Levinson moving to lead independent director. Cook remains CEO through the end of August 2026 (Apple Newsroom).
Why people ask
The question is driven almost entirely by one moment. On December 3, 2018, accepting the ADL's first Courage Against Hate Award, Cook opened with a line of Hebrew from Leviticus and built his remarks around it. He told the audience the work "moves us not to be bystanders as hate tries to make its headquarters in the digital world," and warned, as TechCrunch reported from the same address, "I sometimes say that I worry less about computers that think like people and more about people that think like computers, without values or compassion, without concern for consequences" (TechCrunch). A CEO quoting Torah in Hebrew reads to many viewers as a personal statement of faith. It was not one. JTA, covering that very speech, noted in the same breath that Cook is not Jewish.
The second driver is his job. Apple has deep engineering operations in Israel, and people sometimes read a leader's business relationships as a clue to his background. A common surname invites the same guesswork. Neither is evidence of anything, and neither belongs in an answer to this question. The documented facts are simple: Cook described his own Baptist baptism on the record, and nothing in the reputable record points anywhere else.
Tim Cook and Israel
Cook visited Israel on February 25, 2015, opening Apple's R&D center in Herzliya and meeting President Reuven Rivlin and former President Shimon Peres, per the Times of Israel. He said he has "enormous admiration for Israel, not just as an important ally for the US, but as a place to do business," and Rivlin told him, "You are an inspiration for us to do even more" (Times of Israel). Apple's Israel footprint began with its 2012 acquisition of Haifa-based Anobit, and Herzliya was later described as the company's second-largest R&D site. In October 2023 Cook told Apple employees he was "deeply saddened by the devastating attacks in Israel," according to The Jerusalem Post.

The bottom line
Tim Cook is not Jewish. He was baptized in a Baptist church as a child, said so himself in print in 2015, and no reputable source documents Jewish parentage, ancestry, or conversion. What the record does show is a long public engagement with antisemitism and with Israel, including a Hebrew-quoting ADL keynote in 2018 and an R&D center opening in Herzliya in 2015.
