Phillip Nicholas Angelides /ˌændʒəˈliːdɪs/ AN-jə-LEE-dis; born June 12, 1953) is an American politician and real estate developer who served as the California State Treasurer from 1999 to 2007. A member of the Democratic Party, Angelides was the party's nominee for Governor of California in 2006. Angelides later served as the chair of the Financial Crisis Inquiry Commission, which was charged with investigating the causes of the 2008 financial crisis and presenting a report on their findings to the United States Congress.

Phillip Nicholas Angelides was born in Sacramento, California, on June 12, 1953, to Helen (née Papadopoulos) and Jerry Angelides, who were Greek immigrants. Growing up, Phil and his brother Kimon were encouraged by their father to learn about geography and the United States government. Their father would quiz them weekly on these topics.

Angelides was educated at The Thacher School in Ojai, California and graduated from Harvard University in 1974, majoring in government as a Coro Foundation Fellow.

Angelides' interest in politics was ignited in 1971, during his college freshman year, when he met anti-war activist Allard Lowenstein. In 1973, while in college, Angelides unsuccessfully ran for Sacramento City Council against a popular incumbent. From 1975 to 1983, Angelides worked for California's Housing and Community Development agency. During that time, he again ran unsuccessfully for city council in 1977.

Angelides was an early supporter and fundraiser of the eventual 1988 Democratic Presidential Nominee, Michael Dukakis, and maintains a strong friendship to the present. Dukakis has referred to Phil as "one of the five or 10 best people in American politics today." His work with Dukakis led him to serve as the chairman of the California Democratic Party from 1991 to 1993.

Angelides was appointed president of AKT Development Corp. (a company owned by one of his business mentors, Angelo Tsakopoulos) in 1984. In 1986, Angelides founded his own land development company, River West. Angelo Tsakopoulos, Angelides' former business partner, has been a major campaign donor to California office-holders, who, together with Angelides as chair of the California Democratic Party in the early 1990s, disbursed millions of dollars to Democratic candidates. Tsakopoulos has donated over $3,200,000 to Angelides' campaigns beginning in 1993 and for the 2006 gubernatorial race, Tsakopoulos has donated $3,750,000 to Mr. Angelides with his daughter, Eleni Tsakopoulous-Kounalakis donating $1,250,000.

Angelides' development firm, River West, is most known for development in a floodplain called Laguna West, which is located outside Sacramento in Elk Grove, California. Laguna West was one of the first developments designed along the principles of New Urbanism. For this project, as well as his history of promoting New Urbanism, Angelides was honored with a Lifetime Achievement Award from the Congress for the New Urbanism on June 11, 2005. However, since completion, the development at Laguna West has been described as a "catastrophic failure" that replicates many of the features of conventional suburban sprawl. The Sierra Club has described Laguna West as a "conventional suburb."

Angelides first ran for State Treasurer in 1994, losing in the general election to Matt Fong. He served as Co-Chair of the Sacramento Mayor's Commission on Education and the City's Future from 1995 to 1996. He then ran again for State Treasurer in 1998 as a Democrat and won, and was re-elected in 2002.
