No, there aren't.
http://en.wikipedia.org/wiki/Trillionaire"A trillionaire is a person who has a net worth of at least one trillion units of currency, such as United States dollars, U.K. pounds, euro, or Zimbabwean dollars. One trillion is 1,000,000,000,000.
Before the Reserve Bank of Zimbabwe removed 12 zeros from the dollar, everyone legally entitled to posses currency in the country was a trillionaire in local currency terms because of the 10, 20, 50 and 100 trillion dollar banknotes. Now the trillionaires are gone."
