James "Jamie" Dinan (born 1959) is an American hedge fund manager and founder of York Capital Management.


James Gerard Dinan was born to a Roman Catholic family in 1959 in Baltimore, Maryland, one of five children of Robert and Jeannette Dinan.[2] His father was a textile engineer and his mother a homemaker.[2] In 1969, the family moved to Worcester, Massachusetts.[2] Dinan graduated from the private Bancroft School[2] and then went on to earn a B.S. from the Wharton School of the University of Pennsylvania with a degree in economics. While at the University of Pennsylvania, Dinan joined Alpha Chi Rho, a northeastern fraternity.[2]


In 1981, he took a job with stock research firm, Donaldson, Lufkin & Jenrette (DLJ)[2] and later earned a M.B.A. from Harvard University.[1] In 1985, he took a job at the merger arbitrage firm Kellner DiLeo & Company.[2] In 1987, the market crashed and he lost his entire $600,000 in savings.[2] In 1991, he was able to raise $3.6 million from his former DLJ colleagues and started his own hedge fund named York Capital (named after the street he was then living on, York Avenue).[2] In 1993, his fund earned credibility with a 33.8 percent return and by 2000, the fund had over $610 million in assets.[2] In 2010, he sold 33% of York to Credit Suisse for $425 million.[1] In 2011, he made a $1 million donation to the Museum of the City of New York.[3] In July 2014, Dinan gained partial ownership of the NBA's Milwaukee Bucks.[4]

Dinan is married to Elizabeth R. Miller,[5][6] and they have three children together.[1] Dinan lives in Manhattan and also owns homes in Westchester County, New York; Nantucket, Massachusetts; and on the Caribbean island of Saint Barthélemy.[2]
