Jan Bonde Nielsen (born 20 May 1938) is a Danish oil tycoon.Between 1947 and 1980, Nielsen was a member of the Executive Board of Burmeister & Wain.
He moved to London in 1981 after filling a bankruptcy.In 1982, in the so-called "Bonde Nielsen case", Nielsen, who was then residing in England, was indicted for a fraud in connection with the transfer of shares.
In 1986, he was acquitted by the Copenhagen City Court, but the prosecution appealed the case.
Due to Nielsen's absence and, according to English criminal law, he could not be extradited, the Østre Landsret had to postpone the case.
