Robert John Hugin (born July 23, 1954)[1][2] is an American businessman who was formerly the executive chairman of Celgene, a biopharmaceutical company.

[5][6] In 2020, he ran for chairman of the New Jersey Republican Party, but was defeated by former Hackettstown mayor Michael Lavery.

After graduating, Hugin served in the United States Marine Corps as an active duty infantry officer from 1976 to 1983.

[14] At Princeton, Hugin was president of the male-only Tiger Inn, a highly selective private eating club on campus.

"[15] Later, as president of the alumni board of Tiger Inn, he led the club's opposition to a 13-year series of lawsuits during the 1980s and 1990s to require the club to admit women, describing the legal campaign to "politically correct fascism”.

[4] In his time at Celgene the market capitalization of the company went from $100 million to $70 billion, and headcount grew to 6,000.

[25] On his 2018 campaign website for the U.S. Senate seat in New Jersey, Hugin described himself as a "different kind of Republican", "moderate" and "independent".

[29] Hugin announced that he is pro-choice on abortion and supports same-sex marriage in a campaign ad.

[31] He supported the nomination of Supreme Court Justice Neil Gorsuch and has said he would support similarly conservative judicial Supreme Court candidates, causing some to question whether he would be proactive about defending abortion rights.

[33] He opposed the Trump administration family separation policy, and announced that he supports a pathway to citizenship for some undocumented immigrants.

[40][41] Hugin also acted as a delegate supporting Trump's nomination at the 2016 Republican National Convention.
