Christopher Bancroft Burnham (born 1956)[1] is an American business executive, public servant, and politician.

[6] Burnham was elected Connecticut State Treasurer in 1994,[8] defeating the Democratic incumbent Joseph M. Suggs Jr. Burnham resigned effective July 22, 1997, to become president and chief executive officer of Columbus Circle Investors, an investment firm based in Stamford, Connecticut.

Because Burnham had previously hired the firm to manage $150 million of the state's pension funds, his decision to join the company came under criticism.

[7] In 2020, Burnham was nominated by President Donald Trump to be the member of the Federal Retirement Thrift Investment Board (FRTIB).

He established the first UN Ethics Office, the first United Nations Independent Audit Advisory Committee, the adoption of new International Public Sector Accounting Standards, the first comprehensive consolidated annual report in the history of the United Nations, and a new whistleblower protection policy that received independent recognition as the “gold standard.”[13] During his time as under secretary general for management at the UN, Burnham uncovered extensive evidence of fraud involving the purchase of equipment for peacekeeping operations amounting to tens of millions of dollars.
