Julian Hart Robertson Jr. KNZM is an American investor, hedge fund manager, and philanthropist. Now retired, Robertson invests directly in other hedge funds, most run by former employees of Robertson's defunct hedge fund company.

Robertson was born in Salisbury, North Carolina. He founded the investment firm Tiger Management Corp., one of the earliest hedge funds. Robertson is credited with turning $8 million in start-up capital in 1980 into over $22 billion in the late 1990s, though that was followed by a fast downward spiral of investor withdrawals that ended with the fund closing in 2000.

In 1993, his compensation and share of Tiger's gain exceeded $300 million. His 2003 estimated net worth was over $400 million, and in May 2015 it was estimated by Forbes at $3.4 billion. Robertson said in 2008 that he shorted subprime securities and made money through credit default swaps. The following year, according to Forbes, Robertson's return on his $200 million personal trading account was 150 percent.
