James White (17 May 1877 – 29 June 1927) was an English financier, property developer and speculator. From a working-class family in Lancashire, he worked at a number of jobs before becoming well known in the years before the First World War as a boxing promoter. From that, he moved into property and other transactions, making large sums of money in major deals. He became a racehorse owner and theatre proprietor.
White finally overreached himself financially, and being unable to meet his huge liabilities, committed suicide at the age of 50.
