John Philip Mohr (20 April 1910 – 25 January 1997) was an administrator with the Federal Bureau of Investigation.
As Assistant to the Director for Administrative Affairs, he was one of the officials chiefly responsible for the proper implementation of procurement requirements and procedures.
He retired on 30 June 1972 as the FBI's No.
In January 1978, United States Attorney General Griffin Bell issued a public report summarizing an investigation into alleged misuse of FBI funds in a "Confidential Fund."
Mohr, Clyde Tolson, and FBI Director J. Edgar Hoover could authorize disbursements from this fund, and it was found that Mohr had directed employees of the Exhibit Section to make numerous repairs and improvements of property owned by him and his family.
