Daniel Howard Yergin is an American author and consultant within the energy and economic sectors. Yergin is vice chairman of S&P Global. He was formerly vice chairman of IHS Markit, which merged with S&P in 2022. He founded Cambridge Energy Research Associates, which IHS Markit acquired in 2004. He has authored or co-authored several books on energy and world economics, including the Pulitzer Prize–winning The Prize: The Epic Quest for Oil, Money, and Power, (1991) The Quest: Energy, Security, and the Remaking of the Modern World (2011), and The New Map: Energy, Climate, and the Clash of Nations (2020).

The Prize: The Epic Quest for Oil, Money, and Power is Daniel Yergin's 1990 history of the global petroleum industry from the 1850s through 1990. The Prize became a bestseller, helped by its release date in December 1990, four months after the invasion of Kuwait ordered by Saddam Hussein and one month before the U.S.-led coalition began the Gulf War to oust Iraqi troops from that country. The book eventually went on to win a Pulitzer Prize.
