Thomas Fahr "Tom" Steyer (born June 27, 1957) is an American hedge fund manager, politician, philanthropist, and environmentalist. Steyer is the founder and former Co-Senior Managing Partner of Farallon Capital Management, LLC and the co-founder of Beneficial State Bank. Steyer was on the Board of Trustees at Stanford University from 2012 to 2017.
Steyer unsuccessfully ran for the Democratic nomination for President of the United States in 2020. He also unsuccessfully ran for Governor of California in the 2026 gubernatorial election.
Steyer was born in Manhattan, New York City. His mother, Marnie (née Fahr) was a teacher and his father, Roy Henry Steyer was a law firm partner and was a prosecutor at the Nuremberg Trials.
Steyer grew up on the Upper East Side of Manhattan. He graduated from Yale University summa cum laude in economics and political science. Steyer received his MBA from Stanford Graduate School of Business.
In 2017, Steyer spent around $10 million for a television ad campaign advocating the impeachment of President Donald Trump and plans to spend millions more on a digital ad campaign to call for Trump's impeachment. Steyer thought about running for Governor of California in the 2018 gubernatorial election as a stance against President Trump.

On July 9, 2019, Steyer announced his candidacy for President of the United States in the 2020 election. He stated that he would be running in the Democratic primaries in an online campaign video. He dropped out of the race after losing the South Carolina primary on February 29, 2020. Steyer spent $250 million of his own money on his campaign. This was more than any other candidate in history, except Mike Bloomberg's campaign.
In 2023, Steyer held a fundraiser for President Joe Biden's re-election campaign for president in his San Francisco home.
In November 2025, Steyer announced his candidacy for Governor of California in the 2026 gubernatorial election.
In March 2026, Steyer's campaign wanted the California Secretary of State to remove U.S. Representative Eric Swalwell from the ballot. He said that Swalwell is not a California resident and that he is a resident of Washington, D.C. The petition was denied. Swalwell later ended his campaign after being accused of sexual harassment. Steyer's campaign quickly became the highest-spending 2026 gubernatorial campaign in California.
On June 2, 2026, Steyer finished in third place in California's nonpartisan primary. He did not advance to the November runoff. He lost to Democrat Xavier Becerra and Republican Steve Hilton.
In August 1986, Steyer married Kathryn Ann Taylor. They have four children, Samuel Taylor ("Sam"), Charles Augustus ("Gus"), Evelyn Hoover ("Evi"), and Henry Hume ("Henry"). They live in San Francisco, California.
Steyer has two brothers: Hume Steyer, an attorney in New York City and Jim Steyer, an attorney, author, and Stanford University professor.
Steyer has a net worth of $1.6 billion. Steyer wears tartan neckties every day, because in his words “You gotta dress up for a fight.”
