Christine Temple Whitman (née Todd; born September 26, 1946) is an American politician and author who served as the 50th governor of New Jersey from 1994 to 2001 and as Administrator of the Environmental Protection Agency under President George W. Bush from 2001 to 2003. Until 2025, upon the election of Mikie Sherrill, Whitman was the only woman to have served as governor of New Jersey.

Born in New York City to a Republican political family, Whitman graduated from Wheaton College in 1968 and began her political career in the Nixon administration's Office of Economic Opportunity. After coming within three percentage points of unseating U.S. Senator Bill Bradley in 1990, she ran for governor of New Jersey, defeating Democratic incumbent Jim Florio. A self-described Rockefeller Republican, Whitman defeated Democrat Jim McGreevey to win re-election in 1997. She remained governor until stepping down in 2001 to become Administrator of the Environmental Protection Agency, where she served until 2003. During her tenure at the EPA, Whitman was noted for having assured the public that the air in lower Manhattan was safe to breathe following the terrorist attacks of September 11, 2001; she apologized in 2016 for having made this statement.

In 2022, Whitman joined former Democratic presidential candidate Andrew Yang to form the Forward Party, a centrist third party.

Christine Todd Whitman was born Christine Temple Todd in New York City on September 26, 1946. Her mother was Eleanor Prentice Todd (née Schley) and her father businessman Webster B. Todd. Both the Todds and the Schleys were wealthy and prominent New Jersey political families. The Schleys were among the first New Yorkers to move to the area that later became Far Hills, New Jersey, which became a popular suburb for wealthy, moderate Republicans. Webster B. Todd amassed a fortune as a building contractor on projects including Rockefeller Center and Radio City Music Hall. He used his wealth to donate to Republican politicians, becoming an advisor to Dwight D. Eisenhower and chairing the New Jersey Republican State Committee twice. Eleanor Prentice Todd served as a Republican national committeewoman, led the New Jersey Federation of Republican Women, and served as vice chair of the Republican National Committee. Eleanor Prentice Todd's political activity caused a newspaper to speculate that she could be a viable candidate for governor, although she never chose to run for office.

Christine Todd grew up on her family's farm, Pontefract, in Oldwick, New Jersey. She had three older siblings, including brothers Webster and Danny. At the age of nine, she attended the 1956 Republican National Convention and met President Eisenhower. As a child, Todd attended Far Hills Country Day School before being sent to boarding school at Foxcroft in Virginia. Todd disliked being so far away from home and after a year, she transferred to the Chapin School in Manhattan, allowing her to return home on the weekends.

After graduating from Wheaton College in 1968 with a Bachelor of Arts degree in government, Todd worked for Nelson Rockefeller's presidential campaign.

Christine Todd married John Whitman in 1974. Christine Todd Whitman worked for the Office of Economic Opportunity and the Republican National Committee.

Whitman served on the board of trustees of Somerset County College (later renamed Raritan Valley Community College). Elected to two terms on the Somerset County Board of Chosen Freeholders, she served for five-and-one-half years beginning in 1983. From 1988 to 1990, during the tenure of Gov. Thomas Kean, she served as president of the New Jersey Board of Public Utilities.
